Muslim Brotherhood cancels marches due to sniper threat [UPDATE] CAIRO, Aug. 18 (UPI) -- The threat of rooftop snipers led the Muslim Brotherhood to call off a series of protest marches around Egypt Sunday. Egypt was braced for another day of angry street clashes between security forces and supporters of ousted president Mohamed Morsi, led by the Muslim Brotherhood. Brotherhood leaders abruptly canceled the marches, saying they feared the protesters could be fired on by snipers in buildings along the routes, CNN said. The Egyptian interim government installed by the military after Morsi's removal leveled the blame for the street violence on outside agitators. Officials also were considering legal steps to disband the Muslim Brotherhood altogether. Minister of Social Solidarity Ahmed al-Borai said Sunday an official decision would be made by the government in 15 days after the issue is studied by the General Federation of non-governmental Organizations, the Egypt Independent reported.
