Four people were injured in protests in Cairo and Giza on Friday, the Egyptian Health Ministry said.
Head of Ambulance Authority Ahmed Al-Ansary said that three people were injured in Giza and one in Cairo. They were all transported to hospitals for treatment.
Limited clashes broke out between supporters of deposed president Mohamed Morsi and their opponents in Al-Haram area in Giza. Similar scuffles took place between pro-Morsi protesters and police in Cairo's Masr El-Gedida neighborhood.
Demonstrators took to the streets in several governorates nationwide in protest of Islamist president Mohamed Morsi's ouster.
Police intervened to disperse the marches and clashes in Suez, Alexandria and Gharbiya.
According to Ahram's Arabic news website, eyewitnesses claimed that six people had been injured in the Nile Delta's Gharbiya.
The National Coalition in Support of Legitimacy, a pro-Morsi Islamist coalition, announced a week-long series of protests on Friday dubbed "the Suez resilience, our way to Jerusalem."
This slogan refers to the valient popular resistance of Suez citizens to the 24 October, 1973 Israeli attack on Suez during the October war, according to a statement by the National Coalition in Support of Legitimacy.
"[Mohamed Morsi] supported our just cause in Palestine," the statement continues, "this is why they turned against him and ousted him by force. He was resilient and subsequently framed with the same charges used by Zionists against the resistance, such as the accusations that he was spying for Hamas."
The protests are being staged in condemnation of the current government, which Morsi supporters accuse of carrying out a "coup" against the elected president.
