Egypt Unrest: Death Toll Climbs 750

Supporters of ousted Egyptian president Mohamed Morsi announced new demonstrations on Sunday as the country grew increasingly polarised and the death toll in four days of violence topped 750.
The fresh protests come after a violent standoff between Islamists and security forces at a mosque in central Cairo on Saturday, that briefly turned the area into a battleground.
Security forces traded fire with gunmen inside the Al-Fath mosque before eventually dragging protesters outside, where angry mobs awaited them, chanting "terrorists."
The interior ministry said 385 people inside the mosque had been arrested, and the government gave new death toll figures that brought the number of dead in four days to 751.
Despite the violence, the Anti-Coup Alliance of Morsi supporters said they would hold several rallies in Cairo and elsewhere.
