Kurt Waldheim may have cooperated with U.S. and British intelligence services after World War II in return for having his German army record purged of incriminating evidence, a British newspaper reported Thursday.

A panel of historians has conclud-ed the Austrian president was "in close proximity" to some Nazi atrocities in the Balkans, knew they were going on and made no attempt to prevent them. It also said Waldheim concealed his wartime past and tried to make it seem harmless once he could no longer hide it.The international panel of historians left open the question of whether he was guilty of any crime. Waldheim has denied any wrongdoing.

The Times of London said Thursday today it had unearthed evidence that British wartime documents and subsequent British Foreign Office papers likely to relate to Waldheim's wartime role had been suppressed.
