Poland's Catholic Church is holding a behind-closed-doors conference on ways of preventing child sex abuse by priests, its first major gathering on a problem long ignored.

Abuse victims and experts on child psychiatry and sex abuse from Germany and the U.S. are attending the two-day conference in Krakow.

The media were only allowed to attend the opening Mass on Friday morning, led by Krakow Archbishop Cardinal Stanislaw Dziwisz, who was previously personal secretary to Pope John Paul II.

Dziwisz quoted the pope as saying "there is no room in priesthood or in convent life for those who hurt young people."

Some 30 priests have been convicted of pedophilia in Poland and a few of them are serving prison terms.
