Poland thwarts alleged Russian plot to assassinate US citizen on NATO soil
Warsaw security services arrest suspect in cooperation with Washington, raising alarms over cross-border covert operations

Polish Prime Minister Donald Tusk has confirmed the arrest of a Russian citizen in Warsaw over an alleged plot to assassinate an American citizen of Ukrainian origin. The announcement, made on Thursday, marks a significant escalation in security concerns across Eastern Europe, with Tusk describing the incident as the first known instance of a Russian-level actor attempting to attack a US citizen on the territory of another NATO country.
Tusk stated that the target was considered “inconvenient to the Putin regime,” framing the alleged crime within the broader context of Moscow’s efforts to silence critics abroad. He characterised the thwarted attack as a “very dangerous signal” and praised the rapid response of domestic security forces. “At the last minute, thanks to the action of the Internal Security Agency and the police, we managed to prevent this execution, this attack,” Tusk said.
The suspect was taken into custody on August 7, though Tusk declined to provide specific details regarding the mechanics of the plot or the identity of the intended victim. Polish Minister Tomasz Siemoniak, who oversees security services, confirmed via social media that the operation was conducted in close cooperation with US authorities, underscoring the transnational nature of the intelligence and law enforcement response.
The arrest occurs against a backdrop of heightened tension between Russia and Western allies since the full-scale invasion of Ukraine began on February 24, 2022. European nations have expressed growing alarm over Russia’s aggressive posture, including repeated incursions by Russian military planes near NATO airspace. In response, Poland and several Baltic states bordering Russia have recently ramped up security at key infrastructure sites.
Regional security fears have been further inflamed by recent incidents, including the discovery of an explosive-laden quadcopter drone near a German airport. While German authorities have not officially attributed the device to Moscow, US intelligence suggests Russian involvement. Additionally, Lithuanian Defence Minister Robertas Kaunas has alleged that Moscow is planning “false flag” attacks on regional infrastructure using captured Ukrainian drones to frame Kyiv.
Despite these allegations, Russia continues to deny involvement in cross-border operations, instead accusing Ukraine of carrying out killings of individuals linked to its war efforts. Moscow recently cited an explosion in Crimea that killed a Russian military officer as evidence of Ukrainian aggression. Meanwhile, authorities in France, Lithuania, and Germany have reported breaking up various plots targeting Russian dissidents and individuals linked to the Ukraine war effort in recent years.
