Poland's Prime Minister Donald Tusk announced that a Russian citizen was arrested for plotting to kill a Ukrainian American in Warsaw, marking a troubling first for NATO countries. The suspect, detained on August 7, was allegedly recruited by Russian intelligence to target a man deemed "inconvenient to the Putin regime."12

Tusk emphasized the seriousness of the situation, stating, "At the last minute, thanks to the action of the Internal Security Agency and the police, we managed to prevent this execution, this attack." This incident highlights a growing trend of Russian threats against critics abroad, with Tusk noting, "We must assume that the Putin regime will try to eliminate people who are inconvenient for various reasons, in various places around the world."3

The operation was conducted in cooperation with U.S. intelligence services, according to Tomasz Siemoniak, Poland’s minister overseeing intelligence. Tusk described the plot as a "very dangerous signal" and a significant escalation in Russian aggression, as it marks the first known attempt to target a U.S. citizen on NATO territory.

Experts have warned of a rise in Russian threats, with numerous incidents of political assassinations linked to the Kremlin. Tusk's announcement comes amid a backdrop of increased scrutiny on Russia's actions in Europe, including a series of disrupted plots against various individuals critical of the regime.7
