WARSAW -- A Russian plan to kill a Ukrainian American citizen in Warsaw was thwarted by Poland before it could be carried out, the Polish prime minister said Thursday, adding it was the first time that “someone on the order of Russia” sought to attack a U.S. citizen on the territory of another NATO country. Western officials have previously warned that Russia has stepped up a campaign of targeted killings since President Vladimir Putin’s 2022 invasion of Ukraine, saying they have disrupted several plots across Europe. But Polish Prime Minister Donald Tusk said this incident was unprecedented. The suspect, who was allegedly recruited by Russia’s secret services, was detained by Polish authorities on Aug.7. He will be held in custody for three months, the Warsaw police said in a statement. The Ukrainian American citizen “was uncomfortable for the Putin regime,” Tusk said in a news conference. The operation was carried out in co-operation with U.S. services, said Tomasz Siemoniak, Poland’s minister overseeing intelligence services. He said the targeted victim was a U.S. citizen “of Ukrainian origin.” Officials did not immediately provide further details. The Russian Foreign Ministry did not immediately respond to a request for comment. Western countries believe Russia seeks to undermine Ukraine’s allies Russia has long been accused of targeting its enemies abroad, including by using rare poisons. But intelligence officials previously told The Associated Press that Russia’s security services are now more brazen in their choice of targets, going after Russian activists and foreign supporters of Ukraine as well as military defectors. “We must assume that the Putin regime will try to eliminate people who are inconvenient for various reasons, in various places around the world,” Tusk said on Thursday. He said that Poland and others must be prepared to counter such actions. Western officials see the campaign as connected to Russia’s broader efforts to undermine European countries that support Ukraine. The AP has mapped about 200 acts of sabotage, arson and other disruption across Europe since the start of the war that officials have linked to Russia. President Vladimir Putin told AP in May that Russia is not waging a sabotage campaign against Europe. In 2006, British authorities accused Russia of being behind the killing of former FSB officer Alexander Litvinenko in London in 2006 with radioactive polonium and of attempting to kill former Russian military intelligence officer Sergei Skripal in Salisbury in 2018 with the nerve agent Novichok. German authorities also said Russia organized the 2019 killing of Zelimkhan Khangoshvili, a former Chechen rebel commander who was shot in a Berlin park by Vadim Krasikov, a hitman who was later greeted by Putin after he was exchanged in a spy swap. In June, a Russian artist who was critical of Putin was shot and killed at close range near his home in eastern Poland. Robert Kuzovkov, known by the pseudonym Semyon Skrepetsky was critical of Putin and Tusk said at the time that the killing had the hallmarks of a political assassination. He suggested it was possible Russia was behind it but Polish officials have not yet attributed it to Moscow. Last year French officials disrupted a plot which they believe was aimed at killing Vladimir Osechkin, a Russian exile who lives under police protection and works to help military defectors flee Putin’s war. Lithuanian officials also disrupted a plot last year to kill a Lithuanian supporter of Ukraine and another against a Russian activist. Officials in Germany have similarly broken up two plots: one to target the head of a German weapons company supplying Ukraine, the other against a Ukrainian military official. Polish authorities arrested a man in 2024 in what they said was a plot to assassinate Ukrainian President Volodymyr Zelenskyy. And that same year, a Russian helicopter pilot who defected was killed in Spain -- with Russian operatives the prime suspects. “This campaign is not by accident or chance,” a senior European intelligence official previously told the AP. “There is political authorization.” By Claudia Ciobanu and Emma Burrows, The Associated Press Burrows reported from London.
