SAINT-ETIENNE-DU-ROUVRAY, France (Reuters) - Knife-wielding attackers interrupted a French church service, forced the priest to his knees and slit his throat on Tuesday, a murder made even more shocking as one of the assailants was a known would-be jihadist under supposedly tight surveillance.

As the attackers came out of the church shouting "Allahu akbar" (“God is Greatest”) they were shot and killed by police.
