Yeltsin hands over Kennedy files
President Kennedy's funeral in Washington DC
New information on the assassination of President John F Kennedy could emerge from a stack of Russian intelligence documents handed over by Russia to the US.
The Russian leader, Boris Yeltsin, gave President Clinton about 80 documents related to the assassination, which happened at the height of the Cold War on 22 November 1963.
He married a Russian women, Marina, whom he brought back to the US.
Correspondents say the Russian documents, from presidential and foreign ministry files, could shed light on Oswald's stay.
The documents also include a file on the Soviet government's reaction to President Kennedy's death, the Interfax news agency reported.
The documents were handed over during talks in Cologne between the two presidents, designed to mend relations damaged by Nato's bombardment of Yugoslavia, which was opposed by Russia.
Mr Berger said the documents would be translated from Russian, analysed and "all interesting elements" would be made public.
William Joyce, a former member of the Assassination Records Review Board, also welcomed the disclosure of the documents.
"One hopes that whatever is released will provide maybe a bit more information - fill in a few more gaps - and help us come to a more confident understanding of what happened."
After the collapse of the Soviet Union in 1991, Russia's intelligence agency declassified its files on Lee Harvey Oswald.
But at the time, Russian intelligence officers said the documents shed no new light on the Kennedy assassination.
A year later, Russian media reported that the Russian intelligence chief at the time of the Kennedy assassination wanted to release the files, but was blocked by contemporary spies who feared disclosure of their names and tactics.
