Four men went on trial on Monday over the murder of an elderly priest who was knifed to death at his altar in a militant attack that rocked France.
Father Jacques Hamel was leading morning mass in the Normandy town of Saint-Etienne-du-Rouvray in July 2016 when two attackers stormed in, forced the 85-year-old to his knees and slit his throat. They were both shot dead by police.
