Clashes erupted between opponents and supporters of President Mohamed Morsi in Sharqiya on Monday leaving two injured, Al-Ahram Arabic news website reported.
The groups exchanged volleys of rocks after an opposition protester was injured by pellet shots. A Central Security Forces (CSF) officer suffered a head wound.
It remains unclear what started the violence. There have been a series of clashes between anti- and pro-government protesters across Egypt in recent weeks.
The Muslim Brotherhood’s Freedom and Justice Party (FJP) announced on Facebook that it would be holding an open-ended sit-in alongside 20 other Islamist parties across Egypt from Friday under the slogan “legitimacy is a red line.”
On Monday, an alliance of Islamist parties announced in Cairo that they would be holding an open-ended protest in Rabaa Al-Adawiya Square in Cairo’s Nasr City under the same slogan.
The call for protests by pro-Morsi Islamist groups comes amid plans for mass demonstrations against President Mohamed Morsi, who hails from the Brotherhood, on 30 June, the anniversary of his inauguration, to demand his removal and early presidential elections.
Rebel (Tamarod) was the first group to call for protests on 30 June.
