CAIRO (AP) -- An Egyptian government spokesman says the death toll in Friday's clashes has risen to 173 nationwide.
Shereef Shawki said Saturday that 1,330 people were injured in the fighting.
The Muslim Brotherhood took to the streets Friday in a "Day of Rage" -- ignited by anger at security forces over clearing two sit-in camps earlier in the week, leaving hundreds dead. Those sit-in demonstrations were filled with supporters of President Mohammed Morsi, who was ousted in a coup July 3.
Meanwhile, hundreds of Morsi supporters remained at the al-Fatah mosque in Cairo on Saturday morning after barricading themselves inside overnight. A Muslim cleric there said there were ongoing negotiations with the military to have protesters safely leave.
