Cairo (CNN) -- As was the case exactly two years ago before President Hosni Mubarak's ouster, streets around Egypt were roiled by deadly clashes Friday, pitting protesters against both police and supporters of the nation's current leader. At least seven people were killed, six of them in Suez where gunfire erupted during clashes between anti-government protesters and those loyal to President Mohamed Morsy, according to official media outlets. Four of those killed in Suez had been shot in the abdomen, Health Ministry spokesman Ahmed Omar told state-run EGYNews. It was not clear which group those killed belonged to or who was responsible. The head of security in Suez denied his forces fired on protesters, state TV reported. By Saturday morning, Egyptian armored vehicles were dispersed around Suez at the request of the city's security chief, who had said his forces were fired upon and feared the situation was getting out of control, EGYNews reported.
