Pope Francis joined leaders praising a French police officer who "gave his life out a desire to protect people" during a terrorist attack. Lt. Col. Arnaud Beltrame, 44, had convinced the gunman, identified as Redouane Lakdim, to allow him to take the place of a woman Lakdim was holding hostage on March 23 in a grocery store in Trebes, a small town in southern France. Lakdim had already killed the passenger in a car he had hijacked in the nearby town of Carcassonne and had shot at a group of police who were jogging near their barracks, injuring one of the officers. He then drove to the grocery store and reportedly entered shouting that he was part of the Islamic State group. Lakdim killed the store's butcher and a shopper. Although police managed to get Lakdim to let other shoppers leave, he kept one woman with him as a human shield. Beltrame offered to take her place and, media reported, he left his mobile phone on a table with an open line so that police outside could hear what was happening. When they heard more gunshots, the police stormed the supermarket and killed Lakdim. Beltrame was seriously wounded and died later in a local hospital. Bishop Alain Planet of Carcassonne and Narbonne celebrated a memorial Mass for the police officer March 25 in Trebes. According to the BBC, the bishop compared Beltrame to St Maximilian Kolbe, who died at the Nazis' Auschwitz death camp after volunteering to take the place of another prisoner. Pope Francis sent a message of condolence to Bishop Planet, expressing his sadness over what occurred, entrusting the victims to God's mercy and praying for the families of the victims. "I particularly recognize the generous and heroic act of Lieutenant-Colonel Arnaud Beltrame who gave his life out of a desire to protect people," the Pope told the bishop. "I condemn again such acts of indiscriminate violence which cause so much suffering," the Pope said, and pray to God for the gift of peace.
