Meanwhile, Pope Francis has spoken out against the role of the weapons industry in Tuesday’s deadly attack on Brussels. The pope spoke during pre-Easter rituals north of Rome on Thursday.

Pope Francis: “Muslims, Hindus, Catholics, Copts, Evangelists, but brothers, children of the same god, who want to live in peace, integrated. Three days ago, there was a gesture of war, of destruction, in a city of Europe from people who don’t want to live in peace. Behind that gesture there were arms manufacturers, the arms traffickers who want blood, not peace, who want war, not brotherhood.”
