A journalist targeted by a Russian spy ring said it had a list of "assassination methods" to kill him that was "beyond any imagination." Christo Grozev told the BBC the group "fantasized" about his death, and talked about using a sledgehammer and even a "suicide bomber" to target him. The Bulgarian, who has published several exposs on Russia with colleague Roman Dobrokhotov, said several incidents showed the pair were tracked across Europe and had agents "breathing down our necks." Grozev was speaking after three Bulgarian nationals were found guilty last week of spying for Russia one of the largest foreign intelligence operations in the UK.
