Pope Francis declared that "the world is at war" on Wednesday, a day after two knife-wielding attackers linked with ISIS stormed a French church and slit the throat of a priest. He said this was "not an organic war, perhaps. It's organized, but not organic. But it's war." He said the conflict was not "a religious war," adding that "all religions preach peace — it's the others who want war." Tuesday's attack saw two assailants armed with knives storm a church in Saint-Etienne-du-Rouvray and cut the throat of 85-year-old Father Jacques Hamel. Officials said the two attackers shouted "Allahu Akbar" before being shot dead by security forces.
