Russian President Vladimir Putin said after extending his rule in an election that stifled opposition that Moscow will not relent in its invasion of Ukraine and plans to create a buffer zone to help protect against long-range Ukrainian strikes and cross-border raids.
The Kremlin's forces have made battlefield progress as Kyiv's troops struggle with a severe shortage of artillery shells and exhausted frontline units after more than two years of war. The frontline stretches over 1,000 kilometres (620 miles) across eastern and southern Ukraine.
Advances have been slow and costly, and Ukraine has increasingly used its long-range firepower to hit oil refineries and depots deep inside Russia. Also, groups claiming to be Ukraine-based Russian opponents of the Kremlin have launched cross-border incursions.
"We will be forced at some point, when we consider it necessary, to create a certain 'sanitary zone' on the territories controlled by the (Ukrainian government)," Putin said late Sunday.
This "security zone," Putin said, "would be quite difficult to penetrate using the foreign-made strike assets at the enemy's disposal."
He spoke after the release of election returns that showed him securing a fifth six-year term in a landslide in an election devoid of any real opposition following his relentless crackdown on dissent.
Monday marks the 10th anniversary of Russia's seizure of Ukraine's Crimea Peninsula, which set the stage for Russia to invade its neighbour in February 2022. However, Putin has been vague about his goals in Ukraine since that full-scale invasion floundered.
Putin again warned the West against deploying troops to Ukraine. A possible conflict between Russia and NATO would put the world "a step away" from World War III, he said.
French President Emmanuel Macron recently said that sending Western troops into Ukraine should not be ruled out, though he said the current situation does not require it.
Commenting on the prospects for peace talks with Kyiv, Putin reaffirmed that Russia remains open to negotiations but won't be lured into a truce that will allow Ukraine to rearm.
However, Ukrainian President Volodymyr Zelenskyy has apparently shut the door on such talks, saying Putin should be brought to trial at the International Criminal Court in The Hague, which last year issued an arrest warrant for Putin on war crime charges.
With crucial U.S. aid being held up in Washington, U.S. Sen. Lindsey Graham visited Kyiv on Monday. Ukraine desperately needs the around US$48 billion that the package of support would provide, especially artillery shells and air defense systems.
Graham said he discussed the issue with Zelenskyy and suggested that aid in the form of a no-interest loan might get more more support from U.S. voters. He also denounced the result of Russia's presidential election as "not legitimate" and said he wanted to introduce legislation in the U.S. that would deem Russia a state sponsor of terrorism.
Ukraine's air force said it intercepted 17 out of 22 Shahed drones launched by Russia over various regions of the country overnight. Russia also fired five S-300/S-400 missiles at the Kharkiv region and two Kh-59 at the Sumy region, both in northeastern Ukraine, it said.
Authorities say the intensity of ground attacks and airstrikes has increased recently in the Sumy region, prompting the evacuation of 56 people, including 26 children, from one border village over the past week.
In the past two and a half months the region has been struck more than 3,000 times, after some 8,000 strikes over all of last year, the Ukrainian regional government says. The number of aerial bomb attacks has tripled, and Russian saboteurs are highly active, according to officials.
This story corrects the name of the court to the International Criminal Court.
