Egypt hit by terror attacks in response to deadly shootings by security forces Although there has been a pronounced rise in militant activity across the country since Mr Morsi was deposed in the July 3 military takeover, attacks have mostly concentrated on security installations in the restive North Sinai region. The spread of violence to South Sinai, home to many popular tourist resorts, is a worrying sign in a country which has long earned much of its revenue through tourism. Monday's attacks, all occurring within the space of a few hours, suggest a more coordinated campaign to target state security installations than had previously been apparent. They came the day after holiday celebrations commemorating the anniversary of the 1973 Yom Kippur war ended in ugly clashes between police and opponents of the military takeover. Fifty-three people, most if not all Morsi supporters, were killed in one of Egypt's bloodiest days since the July coup.

Black-clad riot police fired tear gas, rubber bullets and live ammunition into the crowd. Video footage also showed injured protesters being beaten as they were dragged away by police. According to eyewitnesses, the violence began when police fired tear gas on the vociferous march. "I didn't see any provocation from the protesters, the atmosphere was good," said Mosa'ab Elshamy, a photographer on the scene. By nightfall, 46 bodies had reached Cairo's morgues and the Dokki streets were littered with broken glass. Most of the dead had suffered gunshot wounds to the upper body. No security personnel were killed, though several witnesses seeing some among the protesters carrying guns.

Many expressed incomprehension at the previous day's events. "My son should not be dead, he was only marching for what he believed in," said Marwa el Abd, the mother of a 17-year-old boy, Ahmed, who she says was shot by security forces. His friends lost him when the police opened fire. When they found his body, he'd been shot in the neck. Egypt's military leader General Abdel-Fattah el Sisi responded to the violence with a late night speech promising to fulfil "the people's mandate to confront terrorism." He said: "We will protect Egypt and the Egyptians, this is a promise." Attempts to curb Egypt's rising militancy have largely taken the form of a military operation in North Sinai, close to the Gaza Strip. Local residents complain that hundreds of homes have hit as "collateral damage."
