At least 17 people were injured late on Monday when clashes erupted between supporters of deposed president Mohamed Morsi and opponents in the Suez Canal city of Ismailia.
Clashes erupted in Ismailia when a march of Morsi supporters approached the security directorate headquarters. The protesters and their opponents clashed using gunshots and stones leaving 17 people injured, including seven with birdshot wounds.
The police fired teargas in an attempt to end the clash.
Morsi supporters, led by the Muslim Brotherhood, marched to security directorates in governorates nationwide to protest what they describe as "police brutality" during Cairo's Nasr City clashes on Saturday that left at least 80 dead and hundreds injured.
These marches ended violently in a number of governorates.
In the Nile Delta City of Mansoura violence broke out after police forces prevented the pro-Morsi march from reaching the security directorate.
According to Al-Ahram Arabic news website, there were around 5,000 protesters chanting against Defence Minister Abdel Fattah El-Sisi, calling for the reinstatement of Morsi as president. Police also fired teargas when the violence erupted. Two cars were destroyed in the melee.
Morsi supporters and opponents have frequently faced off since his removal by the army on 3 July amid mass protests against him. At least 200 dead and hundreds were injured as a result in the past few weeks.
Both camps have used firearms against one other, among other weapons, on numerous occasions.
