The security agency released footage of an interrogation of the man, in which he recounts how he and his wife moved to Ukraine in 2020 “in search of a better life.” However, the couple soon found themselves pressed for cash and harassed by the immigration authorities, the person in the video says. The suspect claims that Ukrainian intelligence officers contacted them and eventually recruited them for an assassination plot in Russia.According to the FSB, the individual retrieved an explosive device as well as video surveillance equipment from a cache in Moscow Region, and was supposed to plant the bomb under a senior Russian military officer’s car.
