Ukraine’s state security service said it thwarted another Russian plot to assassinate Ukrainian President Volodymyr Zelensky, resulting in the arrests of two Ukrainian colonels, writes axios.com.

The Ukrainian claims could not be independently verified. The Security Service of Ukraine (SBU) said Tuesday the plot involved networks of agents organized by Russia’s Federal Security Service (FSB). It said the agents attempted to recruit members of Zelensky’s security detail who would take the president hostage and later kill him. The SBU claimed the plot was run from Moscow and released the names of 3 Russian spies allegedly behind the conspiracy.

At least 2 Ukrainian colonels with the State Protection Service, the main agency that provides security for Ukraine’s president and other ministers and officials, were accused of participating in the plot against Zelensky and were arrested on suspicion of treason. The SBU said one of the colonels brought drones, rocket-propelled grenades and anti-personnel mines to Kyiv and had spoken with FSB agents.

The head of the SBU Vasyl Malyuk, head of the Defense Intelligence of Ukraine Kyrylo Budanov and other high-ranking officials were also potential targets, the SBU said. It added that the group planned on killing Budanov, before Orthodox Easter on May 5 by pinpointing his location and attacking it with rockets, missiles and drones.
