VATICAN CITY - Pope Benedict on Wednesday reaffirmed his "full and unquestionable solidarity with Jews" in an attempt to relieve tensions with Jews after a Catholic bishop denied the Holocaust.

Speaking at his Wednesday audience, the pope said the attempt to exterminate the Jews in the Holocaust should remain a warning for all people.

Briton Richard Williamson, one of four traditionalist bishops whose excommunications were lifted last week, denies the full extent of the Holocaust of European Jews. He has said: "I belive there were no gas chambers."
