Hundreds of Christians and Muslims are hurling stones at each other in downtown Cairo hours after mobs set fire to a church in violence that killed 12 people and injured more than 200.
Christian activist Bishoy Tamri said Muslim youths attacked a large crowd of Coptic Christian protesters marching from the headquarters of the general prosecutor to the state television building overlooking the Nile. He added scores have been injured.
The Christian protesters are accusing the army of collaborating with crowds of ultraconservative Islamists during the earlier attack on a church overnight. A residential building home to Christians was also burned in the overnight violence.
The activist said an army unit securing the television building has not taken action to stop Sunday's renewed clashes.
