In an attack on a protest by hundreds of supporters of ousted Islamist President Mohamed Mursi near Cairo University early Tuesday, one man was killed and 15 people were injured.
Ahram Online, a state-run news website, said police fired tear gas to quell the violence and several cars in the area were destroyed or set on fire.
The Muslim Brotherhood said on the Facebook page of its Freedom and Justice Party (FJP), which Mursi headed before he was elected president in June 2012, that the pro-Mursi protesters were being “terrorized.”
"Leaders of the military coup continue to terrorize the peaceful protesters in Egypt," the FJP said in a statement in English.
The Brotherhood accuses the army of orchestrating a coup that has exposed deep political divisions in the Arab world's most populous and influential nation.
At least four people were killed on Monday in deadly clashes between supporters and opponents of ousted Egyptian president Mohammad Mursi in central Cairo, the health ministry said.
A video posted online showed suspected backers of Mursi opening fire at rival protesters who are camped in Tahrir Square.
At least 26 people were also injured as the rival camps exchanged volleys of stones and birdshot, emergency services said, according to AFP.
Police fired teargas to break up the crowds and Mursi’s foes said the security forces were clearly on their side.
“The police are with us. Those fascists attacked us again. May God punish them,” said Samir Hafiz, 22, with cuts on his hands and face, hurling rocks at the pro-Mursi activists from behind the police line, according to Reuters.
