The Federalnaya Sluzhba Bezopasnosti (Federal Security Service) is the Russian successor to the KGB’s Third 
Chief Directorate. In 1992 President Boris Yeltsin appointed Mikhail Barsukov as its head, but replaced him in 1995 with Nikolai Patrushev. The FSB retains responsibility for counterespionage and counterterrorism, counter drug and people trafficking, and some anti corruption operations.
