Pope John Paul II arrived in Portugal to give thanks to the Virgin of Fatima for saving his life when he was shot 10 years ago. The visit was marked by the discovery of an arms cache near the stadium where the pontiff said Mass.

Shortly after the pontiff arrived Friday, police found the arsenal in a cemetery near the Restelo soccer stadium. Police would not describe the arms.An anonymous caller to the national news agency Lusa said the weapons were left by the terrorist group April 25, also known as FP25, which has renounced violence and is seeking an amnesty for jailed members during the pontiff's visit, according to its supporters.

In his brief address at the airport welcoming ceremony, the pope said he came to Portugal to thank Our Lady of Fatima for saving his life when Turkish terrorist Mehmet Ali Agca shot and wounded him in St. Peter's Square at the Vatican on May 13, 1981.
