As protests in support of ousted president Mohamed Morsi took place around the country on Sunday, a national holiday marking the 1973 war with Israel, clashes erupted in several locations outside the capital.
Six people were injured, including three policemen, in clashes in Suez when security forces fired teargas at a march by pro-Morsi demonstrators, Al-Ahram Arabic news website reported.
Hundreds of protesters were in the pro-Morsi march in Al-Geish Street heading to Al-Arbaeen Square where crowds were demonstrating in support of the army on the 40th anniversary of the 1973 war.
As the march neared the square, clashes broke out between the rival groups, with both sides reportedly using stones and Molotov cocktails.
In Alexandria, clashes broke out between Morsi supporters and residents in Sidi Beshr district after a pro-Morsi march.
Skirmishes also took place in Ismailia between Islamist protesters and their opponents as well as the police near to the local Freedom and Justice Party's (FJP) office, the Muslim Brotherhood's political wing.
In addition, similar clashes were seen in Beheira governorate near Alexandria and in Aswan in the south of the country.
Pro-army demonstrations were reported in Kafr El-Sheikh, Port Said, Sohag, Mahalla, Damietta and other locations.
In Cairo, clashes sparked up in several locations as rival camps took to the streets.
Morsi was deposed by the army on 3 July amid mass nationwide protests against his rule. Since then, his supporters, led by his Muslim Brotherhood group, have been staging demonstrations in protest at what it says was a military coup against Egypt's first democratically-elected leader.
