Two colonels from Ukraine’s State Guard Department (UDO), whose duty was to protect the country’s top officials, were working for Russia’s FSB and plotting to assassinate President Volodymyr Zelensky, said Vasyl Malyuk, head of Ukraine’s Security Service (SBU) in a conversation with journalists, Kyiv Post reports.
“Last year, we carried out a major operation. One of those detained was the head of a department within UDO — someone whose role is to protect this country’s leadership. Alongside him, another colonel was arrested. Both were working for Russia’s FSB, specifically its Fifth Service,” Malyuk said.
According to the SBU chief, the plan was to identify and recruit individuals to assassinate Zelensky at the President’s Office in Kyiv.
“This was an extremely complex operation on our part. We worked on it for nearly two years, essentially from the beginning of the full-scale invasion. We managed to infiltrate the group using a powerful agent-technical operation,” Malyuk said.
He also recalled another attempted assassination, this time in Poland. According to Malyuk, it involved a retired Polish military officer who had been recruited decades ago by the Soviet Union and was recently reactivated as a “sleeper agent” to eliminate Zelensky during his stay at Rzeszów Airport.
