Pope Francis prayed for the victims of the terrorist attack in London at the end of Mass on Pentecost Sunday.

“May the Holy Spirit grant peace to the whole world,” Pope Francis said, according to Vatican Radio. “May He heal the wounds of war and of terrorism, which even this night, in London, struck innocent civilians: let us pray for the victims and their families.”

On Saturday evening three attackers drove a white van into pedestrians on London Bridge before stabbing people in Borough Market. They killed seven people and injured 48 before they were shot dead by police. The three men reportedly shouted “this is for Allah” during the attack.
