Sluzhba Vneshney Razvedki (Служба внешней разведки) (SVR) is Russian for "Foreign Intelligence Service" and is the name of Russia's primary external intelligence agency.
The SVR evolved from the KGB after the collapse of the Soviet Union. In October of 1991, the Centralnaya Sluzhbza Razvedki (or CSR, the Central Intelligence Service) took over the intelligence gathering and analysis duties of the KGB's First Chief Directorate. In December of that year, the former chief of the KGB First Chief Directorate, Yevgeni Primakov, was appointed head of the organisation, which was then renamed SVR.
The SVR performs offensive intelligence gathering operations abroad and also enters into anti-terrorist cooperation and intelligence-sharing arrangements with foreign intelligence agencies.
