Vienna in 1975. Advance notice of this operation "was almost certainly" given to the KGB. A number of notable operations have been conducted by the KGB to support international terrorists with weapons on the orders from the Soviet Communist Party, including: Transfer of machine-guns, automatic rifles, Walther pistols, and cartridges to the Official Irish Republican Army by the Soviet intelligence vessel Reduktor (operation SPLASH) in 1972 to fulfill a personal request of arms from Michael O'Riordan. Transfer of anti-tank grenade RPG-7 launchers, radio-controlled SNOP mines, pistols with silencers, machine guns, and other weaponry to the Popular Front for the Liberation of Palestine through Wadi Haddad who was recruited as a KGB agent in 1970 (operation VOSTOK, "East"). Support of the Kurdistan Workers' Party, in order to destabilize Turkey, a key NATO member during the Cold War. Large-scale terrorist operations have been prepared by the KGB and GRU against the United States, Canada and Europe, according to the Mitrokhin Archive, GRU defectors Victor Suvorov and Stanislav Lunev, and former SVR officer Kouzminov. Among the planned operations were the following: Large arms caches were allegedly hidden in many countries for the planned terrorism acts. They were booby-trapped with "Lightning" explosive devices. One of such cache, which was identified by Mitrokhin, exploded when Swiss authorities tried to remove it from woods near Bern. Several others caches (probably not equipped with the "Lightnings") were removed successfully. Preparations for nuclear sabotage. Some of the allegedly hidden caches could contain portable tactical nuclear weapons known as RA-115 "suitcase bombs" prepared to assassinate US leaders in the event of war, according to GRU defector Stanislav Lunev. Lunev states that he had personally looked for hiding places for weapons caches in the Shenandoah Valley area and that "it is surprisingly easy to smuggle nuclear weapons into the US" either across the Mexican border or using a small transport missile that can slip undetected when launched from a Russian airplane. Extensive sabotage plans in London, Washington, Paris, Bonn, Rome, and other Western capitals have been revealed by KGB defector Oleg Lyalin in 1971, including plan to flood the London underground and deliver poison capsules to Whitehall. This disclosure triggered mass expulsion of Russian spies from London. Disruption of the power supply in the entire New York State by KGB sabotage teams, which would be based along the Delaware River, in the Big Spring Park. An "immensely detailed" plan to
