The Soviet Union stored nuclear weapons in Hungary under a secret agreement with the Kremlin for a possible attack on the West, former Communist Party chief Karoly Grosz confirmed Monday.

Grosz told the newspaper Nepszabadsag he was officially notified nuclear charges were stationed at a base in Hungary when he became premier in 1987.The Soviet Union had admitted only to deploying nuclear weapons in former East Germany and Czechoslovakia, which bordered NATO member West Germany.

Grosz said he went to see Soviet leader Mikhail S. Gorbahev and asked for the removal of the devices from Hungary. Gorbachev promised to comply, but it took "perhaps a whole year" for the Soviets to keep that promise.

The West long suspected that nuclear weapons were deployed in Hungary.
