CAIRO Egypt has hanged four men convicted by a military court of killing three military students in a bombing in 2014, security sources said on Tuesday. It was the second reported multiple execution of convicted Islamist militants in a week. A week ago Egypt hanged 15 men accused of deadly attacks in the Sinai peninsula, believed to be the largest number of people executed in a single day since President Abdel Fateh al-Sisi took power.
