Also, the Russians physically assaulted U.S. embassy personnel who were CIA under diplomatic cover. Right after 9/11, the CIA was on a heavy recruiting campaign so they gave permission for some former agents to tell some (general) stories. The CIA agent who first made contact with Victor Shemov, then a professor at Texas A&M, told us the story of that night. He had to shake his four man KGB tail, don a disguise, and meet Shemov. When he returned to the U.S. embassy, the KGB intercepted him and beat him to a pulp.
