At least 13 killed in Egypt clashes

At least 13 people have been killed over two days of clashes between supporters and opponents of former Egyptian President Mohamed Morsi as of Tuesday, according to the Associated Press.

The military removed Morsi from office on July 3.

Egypt's Health Ministry at first said nine people were killed but later said several people had died from their injuries, reported China Radio International

The death toll was the highest in a single stretch since July 8, when at least 62 people were killed by gunfire from soldiers and police officers who shot at Morsi supporters.

Early Wednesday, an explosion outside a security headquarters in Mansoura in the Nile Delta province of Dakahliya wounded at least 19, including 13 police officers and three civilians, according to AFP.

Police fired at unidentified people inside a nearby abandoned building afterward.

Morsi supporters, who’ve been holding a sit-in near Cairo University to protest the leader’s ouster, said snipers on rooftops shot at them during Tuesday's fighting, BBC News reported.

Thousands of Morsi supporters have been protesting near the university and the Rabaa al Adawiya mosque while Morsi opponents have been demonstrating in Tahrir Square.

Both sides accuse each other of instigating the clashes. Morsi supporters have complained the police don’t protect them when they are attacked.
