Muslim brotherhood members and ousted president Mohammed Morsi supporters light up flares during a demonstration against the military backed government on September 10, 2013 in Cairo, Egypt. A series of attacks in Egypt’s restive Sinai peninsula over the past 24 hours, mostly against soldiers, killed at least four people, security officials said on Tuesday. The violence comes as the Egyptian military presses its campaign in Sinai to quell an insurgency that surged after the army overthrew Islamist president Mohamed Morsi on July 3.
