VATICAN CITY - The longtime private secretary of the late Pope John Paul II has revealed that the pope was wounded in a 1982 knife attack by a priest in Portugal.

Stanislaw Cardinal Dziwisz makes the revelation in `Testimony,' a movie on John Paul's life that was screened for Pope Benedict at the Vatican today.

It was known that John Paul was assaulted by a knife-wielding Spanish priest while visiting the shrine of Fatima in Portugal.

In the movie, Dziwisz says, `Today I can say that that priest wounded the Holy Father.'

John Paul was in Portugal at the time to give thanks for surviving an assassination attempt in 1981, when he was shot by a Turkish gunman in St. Peter's Square.

Dziwisz, now archbishop of Krakow, served the pope from his years as bishop there until his death in Rome in 2005.
