What's happening in Ukraine today and how are countries around the world responding? Read live updates on Vladimir Putin and Russia's invasion of Ukraine.

WASHINGTON -- The United States and its allies are pushing ahead with sanctions aimed at forcing Vladimir Putin to spend Russia's money propping up its economy rather than sustaining its "war machine" for the fight in Ukraine, a top Treasury Department official said Tuesday.

Deputy Treasury Secretary Wally Adeyemo, one of the main U.S. coordinators on the Russian sanctions strategy, said in an interview with The Associated Press that the goal is to make Russia "less able to project power in the future."

On the same day that inflation notched its steepest increase in decades, Adeyemo said reducing supply chain backlogs and managing the pandemic are key to bringing down soaring prices that he related to the ongoing land war in Ukraine, which has contributed to rising energy costs.

Adeyemo discussed the next steps the U.S. and its allies will take to inflict financial pain on Russia -- and the complications the war has on rising costs to Americans back home.

Adeyemo said the U.S. and its allies will next target the supply chains that contribute to the construction of Russia's war machine, which includes "everything from looking at ways to go after the military devices that have been built to use not only in Ukraine, but to project power elsewhere."

KYIV, Ukraine -- More than 720 people have been killed in Bucha and other Kyiv suburbs that were occupied by Russian troops and more than 200 are considered missing, the Interior Ministry said early Wednesday.

In Bucha alone, Mayor Anatoliy Fedoruk said 403 bodies had been found and the toll could rise as minesweepers comb the area.

Ukraine's prosecutor-general's office said Tuesday it was also looking into events in the Brovary district, which lies to the northeast.

Authorities said the bodies of six civilians were found with gunshot wounds in a basement in the village of Shevchenkove and Russian forces are believed to be responsible.

Vladimir Putin vowed Tuesday that Russia's bloody offensive in Ukraine would continue until its goals are fulfilled and insisted the campaign was going as planned, despite a major withdrawal in the face of stiff Ukrainian opposition and significant losses.

WASHINGTON -- The Biden administration is preparing yet another, more diverse, package of military support possibly totaling $750 million to be announced in coming days, a senior U.S. defense official said Tuesday.

The official spoke on condition of anonymity to discuss plans not yet publicly announced.

The additional aid is a sign that the administration intends to continue expanding its support for Ukraine's war effort.

Delivery is due to be completed this week of $800 million in military assistance approved by President Joe Biden just one month ago.

KYIV, Ukraine -- Ukrainian officials say fugitive Ukrainian oligarch Viktor Medvedchuk, who is both the former leader of a pro-Russian opposition party and a close associate of Russian leader Vladimir Putin, has been detained in a special operation carried out by the country's SBU secret service.

In his nightly video address to the nation Tuesday, Ukrainian President Volodymyr Zelenskyy proposed that Russia could win Medvedchuk's freedom by trading Ukrainians now held in Russian prisons.

Ivan Bakanov, the head of Ukraine's national security agency, said on the agency's Telegram channel that Medvedchuk had been detained.

The statement came shortly after Zelenskyy posted on social media a photo of Medvedchuk sitting in handcuffs and wearing a camouflage uniform with a Ukrainian flag patch.

Medvedchuk was the former leader of the pro-Russian party Opposition Platform - For Life. He was being held under house arrest before the war began and disappeared shortly after hostilities broke out.

Putin is the godfather to Medvedchuk's youngest daughter.

KYIV, Ukraine -- Ukrainian President Volodymyr Zelenskyy appealed to the world Tuesday to respond to Russia's use of a poisonous substance in Mariupol.

"Given the repeated threats by Russian propagandists to use chemical weapons against the Mariupol defenders and given the repeated use by the Russian army, for example, of phosphorus munitions in Ukraine, the world must react now," Zelenskyy said in his nightly video address to the nation Tuesday.

Phosphorus munitions cause horrendous burns but are not classed as chemical weapons.

Zelenskyy said experts were still trying to determine what had been used in Mariupol.

Zelenskyy said in addition to the killings in Bucha, more evidence was appearing of the "inhuman cruelty" of Russian soldiers toward women and children in other Kyiv suburbs and other towns in the north and east.

DES MOINES, Iowa - U.S. President Joe Biden on Tuesday said that Russia's war in Ukraine amounted to a “genocide,” accusing President Vladimir Putin of trying to “wipe out the idea of even being a Ukrainian.”

Speaking in Iowa shortly before boarding Air Force One to return to Washington, Biden said he meant it when he said at an earlier event that Putin was carrying out a genocide against Ukraine.

“Yes, I called it genocide,” he told reporters. “It's become clearer and clearer that Putin is just trying to wipe out the idea of even being a Ukrainian.”

Biden added that it would be up to lawyers to decide if Russia's conduct met the international standard for genocide, but said “it sure seems that way to me.”

“More evidence is coming out literally of the horrible things that the Russians have done in Ukraine and we're only going to learn more and more about the devastation and let the lawyers decide internationally whether or not it qualifies,” Biden said.

Biden had previously said he did not believe Russia's actions amounted to genocide, just that they constituted “war crimes.”

MENLO, Iowa -- U.S. President Joe Biden for the first time referred to Russia's invasion in Ukraine as a "genocide" Tuesday.

Speaking in Iowa at an event about steps his administration is taking to staunch rising fuel costs because of the war, Biden termed the conflict, which has seen Russia carry out atrocities against Ukrainian civilians, as a "genocide."

Said Biden: "Your family budget, your ability to fill up your tank, none of it should hinge on whether a dictator declares war and commits genocide a half a world away."

Biden has previously stated that he did not believe Russia's actions amounted to genocide, as Ukrainian government officials have argued, but rather were "war crimes."

WASHINGTON -- Members of the U.S. Congress said the Biden administration and its allies will not stand by if chemical weapons were used in the Russian war with Ukraine.

Lawmakers monitoring developments during a trip to Poland said Tuesday that the U.S. is investigating reports that a poisonous substance had been dropped in Mariupol. But they cautioned that determining the nature of the attack in the beleaguered port city could take time.

"We're taking those reports seriously and I know the United States government and others are trying to determine if that did indeed occur," said Rep. Jason Crow, D-Colo.

Crow said the administration "has been very clear that the use of chemical weapons will not be tolerated."

The Democratic lawmakers, all members of the House Intelligence Committee, are bracing for a potential long war in Ukraine. They said at a press briefing that Congress is looking at next steps in sending additional military and other aid to Ukraine.

In Washington, U.S. Secretary of State Antony Blinken also addressed the reports coming from Mariupol.

"We're not in a position to confirm anything, I don't think Ukrainians are either," Blinken told reporters. "But let me say that we had credible information that Russian forces may use a variety of riot control agents, including tear gas mixed with chemical agents, that would cause stronger symptoms to weaken, incapacitate ... Ukrainian fighters and civilians, as part of the aggressive campaign" in Mariupol.

"We share that information with ... Ukraine and other partners," Blinken said. "And we're in direct conversation with partners to try to determine what what actually is happening."

HE HAGUE, Netherlands -- The global chemical weapons watchdog says it is "concerned by the recent unconfirmed report of chemical weapons use in Mariupol" and is closely monitoring the situation in Ukraine.

The spokesperson for the Organization for the Prohibition of Chemical Weapons says in a statement that the allegations follow "reports in the media over the past few weeks of shelling targeted at chemical plants located in Ukraine, together with accusations levelled by both sides around possible misuse of toxic chemicals."

The spokesperson said in Tuesday's statement that the "use of chemical weapons anywhere by anyone under any circumstances is reprehensible and wholly contrary to the legal norms established by the international community against such use."

Both Russia and Ukraine are among the organization's 193 member states.

The Nobel Peace Prize-winning organization says that it "remains ready to assist any State Party upon its request, in case of use or threat of use of chemical weapons."

WARSAW, Poland -- Germany's president has called on Russia's leader Vladimir Putin to pull out his troops from Ukraine and stop the "barbarity" there as he stressed that Germany will not restore its previous ties with Russia as long as Putin is in power.

Frank-Walter Steinmeier visited Warsaw on Tuesday to talk with Poland's President Andrzej Duda about supporting Ukraine's fight and aiding millions of refugees fleeing the war.

"This barbarity which we see every day must stop," Steinmeier said at joint news conference.

"This can only happen by President Putin ordering his army to stop and I believe that only then (armistice) talks can be successful," Steinmeier said.

"One thing is clear: a return to normal is not possible with Russia under Putin," Steinmeier said, adding that war crimes in Ukraine must be investigated and "those who committed them and those who are politically responsible must be held accountable."

Steinmeier last week admitted mistakes in policy toward Russia in his previous high-ranking jobs, when Germany pursued dialogue with Putin and cultivated close energy ties.

Steinmeier served as ex-Chancellors' Gerhard Schroeder's chief of staff and Angela Merkel's foreign minister. Schroeder is now head of the board of directors of Russia's state oil giant Rosneft.

VIENNA -- Austrian Chancellor Karl Nehammer pledged continued "political and humanitarian support" for Ukraine in a phone conversation with Ukrainian President Volodomyr Zelenskyy on Tuesday, Nehammer said in a statement.

The call came a day after Nehammer became the first European leader to meet with Russian President Vladimir Putin in Moscow.

"It's important to me to immediately inform all key proponents in this conflict about my talks," Nehammer said, according to the statement released Tuesday evening by the Austrian chancellery.

Nehammer said he recounted his meeting in Moscow to Zelenskyy, telling the Ukrainian leader about the most important messages he relayed to Putin.

Among those messages are that the war needs to stop, that those responsible for "serious war crimes" like those committed in the Ukrainian city of Bucha will be held to account, and that the European Union is "as united as it's ever been" on maintaining its sanctions against Russia.

He also told Zelenskyy he believes the continuation of talks in Istanbul are an important step toward bringing an end to the violence, and that Austria will "continue to support all ongoing efforts for peace."

KYIV, Ukraine -- An adviser to Ukrainian president Volodymyr Zelenskyy has paid tribute to Ukrainian troops defending the besieged south-eastern port of Mariupol but acknowledged they are running low on supplies.

Adviser Mykhailo Podolyak wrote on Twitter that "for more than 1.5 months our defenders protect the city from (Russian) troops, which are 10+ times larger. They're fighting under the bombs for each meter of the city. They make (Russia) pay an exorbitant price."

Mariupol was a key target for Russian forces soon after the invasion began in late February. It has symbolic significance as one of the largest cities in eastern Ukraine. It is also strategically valuable as a major harbour and as part of a land corridor between territory held by Russia-backed separatists to the east and the Crimean peninsula, which Russia annexed from Ukraine in 2014.

"Our soldiers remain blocked and have issues with supplies," Podolyak wrote, adding that Zelenskyy and the Ukrainian general staff are working "to find a solution and help our guys." He did not give details, citing operational reasons.

------

KYIV, Ukraine -- The mayor of the Ukrainian town of Bucha, where corpses of civilians with bound hands and gunshot wounds to the head were found after Russian forces pulled out, says 403 bodies have been found so far and that he fears the toll will rise.

"Today, at 10 a.m. we started unearthing the second mass grave, there are 56 bodies there. Plus, there are four private graves. But I'd like to repeat that as of today, we have 403 bodies," Anatoliy Fedoruk told reporters in Kyiv. "Taking into account that our armed forces, our minesweepers are working in the forests between villages and settlements in our territorial community, we hope that those who are missing are still alive but most probably we will find their bodies somewhere between the villages, in those forests."

Fedoruk also said 31 multi-story residential buildings had been destroyed or damaged beyond repair during the war, along with 243 private houses.

BERLIN -- Germany's president says his Polish counterpart suggested that they travel to Ukraine together with other leaders to show solidarity, but "that apparently wasn't wanted in Kyiv."

President Frank-Walter Steinmeier's comments Tuesday, during a visit to Poland, came after German newspaper Bild quoted an unidentified Ukrainian diplomat as saying that he's not welcome in Kyiv at the moment because he had close relations with Russia in the past.

Steinmeier said Polish President Andrzej Duda had suggested that they travel to the Ukrainian capital with the presidents of Lithuania, Latvia and Estonia to send "a strong signal of joint European solidarity with Ukraine." He said he had been prepared to do so.

Steinmeier last week admitted mistakes in policy toward Russia in his previous job as foreign minister.

Steinmeier served twice as ex-Chancellor Angela Merkel's foreign minister, most recently from 2013 to 2017, and before that as ex-Chancellor Gerhard Schroeder's chief of staff. In that time, Germany pursued dialogue with Russian President Vladimir Putin and cultivated close energy ties.

KHARKIV, Ukraine -- A strike hit a what is believed to be a culinary school near the airport in Ukraine's second-largest city on Tuesday, destroying the building and damaging others nearby, according to Associated Press journalists at the scene.

It wasn't clear what hit the building in Kharkiv, with witnesses describing a loud whoosh followed by an explosion. There were no immediate reports of fatalities.

BUCHAREST, Romania -- Romania's President Klaus Iohannis used a speech to his country's delegation of Invictus Games participants on Tuesday to admonish Russian aggression in Ukraine.

"The Russian Federation has been waging war against Ukraine for almost 50 days, and shocking evidence of atrocities and horrors is unimaginable day by day," Iohannis told the wounded and injured military personnel, who will compete in the 2022 Invictus Games set to begin in the Netherlands on Saturday.

"You know best what destruction and loss of life and the dramas of war mean, how much families and communities are affected forever," he said.

Iohannis said that Russia's acts of "horrific, unjustified cruelty" must be punished by the international justice system.

The Invictus Games, an international sporting event for wounded servicemen and women, was launched in London in 2014.

KYIV, Ukraine -- Ukrainian prosecutors are expanding their war crimes investigations in northeastern suburbs of Kyiv after Russian forces withdrew.

Reports of killings of civilians have primarily focused so far on the northwestern suburbs such as Bucha, but the Prosecutor-General's Office said Tuesday it was also looking into events in the Brovary district, which lies to the northeast.

Russian troops advanced into that area last month before retreating to focus on fighting in eastern Ukraine.

The Prosecutor-General's Office said the bodies of six civilians had been found with gunshot wounds in a basement in the village of Shevchenkove and that Russian forces were believed to be responsible.

Prosecutors are also investigating an incident in which they allege Russian forces fired on a convoy of civilians trying to leave by car from the village of Peremoha in the Brovary district, killing four people including a 13-year-old boy. In another incident near Bucha, five people were killed, including two children, when a car was fired upon, prosecutors said.

Prosecutors did not say when they believed the incidents occurred.

MOSCOW -- President Vladimir Putin says that Russians' unity will only grow stronger in the face of Western sanctions and it will be the West that will face instability.

Putin said during a visit to the Vostochny space launch facility in Russia's Far East on Tuesday that the West mistakenly expected its sanctions to undermine Russia's stability. He said that "the Russian people always strengthen their unity in a difficult situation."

He insisted that it will be the West that will be shaken by growing instability, fueled by public dismay over galloping inflation. The Russian leader also lashed out at European leaders, describing them as Washington's stooges and saying that they are conducting policies harmful to their nations.

------

MOSCOW -- President Vladimir Putin says that Russia will press on with its military action in Ukraine until its goals are fulfilled.

Putin said Tuesday that the campaign is going according to plan. He said it is not moving faster because Russia wants to minimize losses.

He said during a visit to the Vostochny space launch facility in Russia's Far East that the "military operation will continue until its full completion and the fulfillment of the tasks that have been set."

Putin claimed that Ukraine backtracked on proposals it made during talks with Russian negotiators in Istanbul, resulting in a deadlock in talks and leaving Moscow no other choice but to press on with its offensive.

------

MOSCOW -- Russian President Vladimir Putin says the Russian economy has successfully resisted new Western sanctions over Ukraine.

Speaking Tuesday on a visit to the Vostochny space launch facility in Russia's Far East, Putin said that Russia's economy and financial system withstood the impact of what he called the Western sanctions "blitz" and the ruble has recovered its losses.

Putin argued that the sanctions will backfire against the West. For example, he said that Western restrictions on fertilizer exports from Russia and ally Belarus will drive up global fertilizer prices, eventually leading to food shortages and increased migration flows.

Putin said that "common sense should prevail" and added that the West should "come back to reason and make well-balanced decisions without losing its face." He contended that "they won't be able to shut all the doors and windows."

He argued that new Western restrictions on high-tech exports will encourage Russia to move faster to develop new technologies, opening a "new window of opportunities."

BOSTON -- Ukrainian officials say a planned cyberattack by Russian military hackers on the country's power grid has been foiled.

They say the country's computer emergency response thwarted an attack planned by hackers from Russia's GRU military intelligency agency that intended to knock electrical substations offline last Friday.

The State Service of Special Communications said on its website that malware was discovered designed to destroy data on computers.

There was no immediate explanation of how the attack was defeated, though the Computer Emergency Response Team of Ukraine thanked Microsoft and the cybersecurity firm ESET in a separate bulletin. Nor was the scope immediately explained.

GRU hackers twice succesfully attacked Ukraine's power grid, in the winters of 2015 and 2016.

Russia's use of cyberattacks against Ukrainian infrastructure has been limited compared to experts' pre-war expectations. In the early hours of the war, however, an attack Ukraine blames on Russia knocked offline an important satellite communications link that also impacted tens of thousands of Europeans from France to Poland.

BRATISLAVA, Slovakia -- Slovakia's government has approved increasing the number of troops in a multinational NATO battlegroup in the country from 2,100 to 3,000.

The first 800 service members have already arrived in Slovakia. The Czech Republic took charge of the battlegroup, with the United States, Germany, the Netherlands, Poland and Slovenia also contributing.

Defence Minister Jaroslav Nad says the increase in the planned troop numbers is related to Patriot air defense systems that the United States, Germany and the Netherlands are deploying in Slovakia.

The move should boost Slovakia's defence capabilities after the country donated its Soviet-era S-300 air defence system to Ukraine last week.

The alliance stationed troops in the Baltic countries -- Estonia, Latvia and Lithuania -- and Poland after the 2014 annexation of Ukraine's Crimean Peninsula by Russia. After Russia attacked Ukraine, NATO decided to boost its presence along the entire eastern flank by deploying forces in Bulgaria, Romania, Hungary and Slovakia.

GENEVA -- The World Trade Organization is predicting that trade in goods will grow much less than previously expected this year, saying prospects for the global economy have darkened since the onset of Russia's war in Ukraine.

The Geneva-based WTO on Tuesday pointed to multiple uncertainties in its forecast over the next two years because Russian and Ukrainian exports of items like food, oil and fertilizers are under threat from the war. It also cited the lingering impact of the COVID-19 pandemic --- notably from lockdowns in China.

Director-General Ngozi Okonjo-Iweala described a "double whammy" from the conflict and the coronavirus. She said the war has caused "immense human suffering" in the region and its effect has rippled around the world, notably in poorer countries.

The WTO said its projections for world trade take into account factors like the impact of the war, sanctions on Russia, and lower demand around the world from lower business and consumer confidence. It said world merchandise trade volume is expected to grow 3% this year, down from a forecast of 4.7% before the war began.

------

MOSCOW -- The Russian military says it has hit Ukrainian arsenals with long-range cruise missiles.

Russian Defence Ministry spokesman Maj. Gen. Igor Konashenkov said Tuesday that the military used air- and sea-launched missiles to destroy an ammunition depot and a reinforced hangar for warplanes at Starokostiantyniv in the Khmelnytskyi region.

Konashenkov said that another strike destroyed a Ukrainian ammunition depot in Havrylivka, near Kyiv.

------

NICOSIA, Cyprus -- The head of Cyprus' Orthodox Christian Church is "unreservedly" condemning Russia's invasion of Ukraine, saying there's "no justification" for Russian President Vladimir Putin to "destroy a country, to raze it to kill."

Archbishop Chrysostomos II told state broadcaster CyBC Tuesday that the invasion is "an unacceptable situation" and that Putin's actions have "no logic." The archbishop said he's distraught that people are being killed and questioned whether the Russian leader is "in his right mind."

The archbishop added that he'd be the "first to go and bless a defensive war," but the "egotism, if not the stupidity" of the Russian leadership "knows no bounds."

Chrysostomos also questioned Putin's embrace of Orthodox Christianity, including the sincerity of his travels to the site where Christians believe Jesus Christ was baptized.

------

KYIV, Ukraine -- Ukrainian police say they have launched a war crimes investigation after a 64-year-old man was killed by a mine left behind in an area from which Russian forces recently retreated.

Police said the unidentified local man was driving Monday near the village of Krasne in northern Ukraine and had pulled over his car to greet acquaintances when he struck an anti-tank mine left at the side of the road.

Ukrainian authorities have issued repeated warnings of mines and explosive traps left in areas where Russian troops have been operating.

------

BERLIN -- German authorities say that more than 330,000 refugees from Ukraine are known to have entered Germany so far.

The Interior Ministry said Tuesday that German federal police have recorded 335,578 people entering since Russia's invasion started on Feb. 24. Those who have arrived are overwhelmingly women and children.

The true number of refugees in Germany could be higher, however, since there are no strict controls on the country's eastern border and Ukrainian citizens can stay up to 90 days in the European Union without a visa. Officials say an unknown number also have moved on to other European countries.

The UN refugee agency on Tuesday put the total number of people who have fled Ukraine at more than 4.6 million, over 2.6 million of whom fled at least initially to Poland.

------

MOSCOW -- President Vladimir Putin says the Russian military action in Ukraine aims to ensure Russia's security and is vowing that its goals will be achieved.

Speaking Tuesday on a visit to the Vostochny space launch facility in Russia's Far East, Putin charged that Ukraine was turned into an "anti-Russian bridgehead" where "sprouts of nationalism and neo-Nazism were being cultivated." Ukraine and its Western allies have dismissed such claims as a cover for aggression.

Putin reaffirmed his claim that the Russian "special military operation" was aimed to protect people in areas in eastern Ukraine controlled by Moscow-backed rebels. He also said that the campaign was also aimed to "ensure Russia's own security."

Putin argued that "we had no other choice" and said that "there is no doubt that we will achieve our goals."

------

MOSCOW -- Russian President Vladimir Putin says that his country can't be isolated.

Speaking on a visit to the Vostochny space launch facility in Russia's Far East, Putin said Tuesday that Russia has no intention to isolate itself and added that foreign powers wouldn't succeed in isolating it.

He said that "it's certainly impossible to isolate anyone in the world of today, especially such a huge country as Russia."

Putin added that "we will work with those of our partners who want to cooperate."

Putin's visit to Vostochny marked his first known trip outside Moscow since Russian launched military action in Ukraine on Feb. 24. Putin toured space facilities together with Belarusian President Alexander Lukashenko.

------

VILNIUS, Lithuania -- Ukrainian President Volodymyr Zelenskyy has urged the European Union to step up economic sanctions against Russia, arguing that the Russian political and military leadership feels it can continue the invasion of Ukraine because of signals from some European nations.

Zelenskyy told lawmakers in Lithuania, a former Soviet republic that is now an EU and NATO member, that "they know they will go unpunished as Europe still prefers continued cooperation, trade, business as usual."

He said via an interpreter that he urges sanctions on all Russian banks and called for Europe to "get rid of their oil,"

In the latest of a series of addresses by video link to parliaments in Europe and beyond, Zelenskyy said that "Europe must win this war. And we will win it together." The 141-seat Seimas assembly was decorated with the blue-and-yellow Ukrainian and the yellow-green-red Lithuanian flags.

HELSINKI -- Telecoms network and 5G technology supplier Nokia says it will exit the Russian market due to Moscow's invasion of Ukraine.

The Espoo, Finland-based company said Tuesday "it has been clear for Nokia since the early days of the invasion of Ukraine that continuing our presence in Russia would not be possible."

Nokia said it has suspended deliveries, stopped new business and moved research and development activities out of Russia in the past weeks.

The company said that Russia accounted for less than 2% of Nokia's sales in 2021, and the exit decision will have no impact on its financial outlook this year.

It said that "as we exit, we will aim to provide the necessary support to maintain the networks and are applying for the relevant licenses to enable this support in compliance with current sanctions."

A spokesman for Moscow-backed separatists in eastern Ukraine has denied using chemical weapons to uproot Ukrainian troops in the port city of Mariupol.

Eduard Basurin was quoted by the Interfax news agency as saying Tuesday that the separatist forces "haven't used any chemical weapons in Mariupol."

Basurin's assertion followed his statement Monday on Russian state TV that the separatists will use "chemical troops" against Ukrainian soldiers holed up at reinforced positions at a giant steel factory in Mariupol "to smoke them out of there."

A Ukrainian unit defending Mariupol claimed without providing evidence that a drone had dropped a poisonous substance on its positions. It indicated there were no serious injuries.

TOKYO -- Japan's Cabinet has approved additional sanctions against Moscow. They include as a freeze on assets of nearly 400 individuals including Russian President Vladimir Putin's two daughters, as well as a ban on new investments and vodka imports.

The new sanctions approved Tuesday include a freeze on assets of 398 Russian individuals, who also include Foreign Minister Sergey Lavrov's wife and daughter. Japan has now frozen assets of more than 500 Russian individuals and organizations.

Japan's new measures also include freezing the assets of major banks Sberbank and Alfa Bank, as well as 28 other Russian organizations such as those linked to military businesses. The measure for the banks will take effect on May 12.

Japan will ban new investment and Russian imports including vodka, wine, lumber and auto parts beginning next week.

Tuesday's approval covers part of a list of sanctions announced last Friday by Prime Minister Fumio Kishida, who also proposed phasing out Russian coal and other fossil fuel imports.

------

LONDON -- A senior British official says "all possible options are on the table" for the West's response if Russian forces use chemical weapons in Ukraine.

Armed Forces Minister James Heappey said Tuesday that neither the U.K. nor the Ukrainian governments had confirmed reports that a chemical weapon may have been used in the besieged city of Mariupol.

Heappey told Sky News that "there are weapons that simply should not be used, and if they are used people will be held to account."

He said: "I think it's useful to maintain some ambiguity ... over exactly what the response would be, but let's be clear, if they are used at all then President Putin should know that all possible options are on the table in terms of how the West might respond."

Britain's defence ministry says Russia continues to redeploy its forces for a push on eastern Ukraine, and fighting is expected to intensify there over the next two to three weeks. It says Russian forces are withdrawing from Belarus in order to redeploy in support of operations in eastern Ukraine.

KIAMBU COUNTY, Kenya -- Russia's war in Ukraine has pushed up fertilizer prices that were already high, made scarce supplies even harder to find and pinched farmers, especially those in the developing world.

Higher fertilizer prices are making the world's food supply more expensive and less abundant, as farmers skimp on nutrients for their crops and get lower yields.

While the ripples will be felt by grocery shoppers in wealthy countries, the squeeze on food supplies will land hardest on families in poorer countries. The fertilizer crunch threatens to further limit worldwide food supplies, already constrained by the disruption of crucial grain shipments from Russia and Ukraine..
