In particular, two colonels of the Ukrainian parole service who passed classified information to the Russians were detained in Ukraine.
One of the tasks of the FSB's intelligence network was to find perpetrators among the military close to the President's security detail who could take the head of state hostage and then kill him. In addition to Zelensky, the enemy planned to eliminate the head of the SBU, Vasyl Malyuk, the head of the Defence Intelligence of Ukraine, Kyrylo Budanov, and other senior officials.
