Morsi supporters march in Cairo

Supporters of Egypt's deposed President Mohamed Morsi are continuing to stage nationwide rallies, with some clashes reported, despite a warning from the Interim prime minister of an imminent crackdown on their protest camps.

Morsi supporters called for 28 marches to begin after Friday afternoon prayers in Cairo as the nation rested on the second day of the Eid al-Fitr holiday, marking the end of Ramadan, and at least four more protests in other parts of Egypt.

"The Egyptian people are continuing, and the days will only increase their determination to persist in their peaceful struggle until the country returns to the democratic path, until the coup is completely ended," the Anti-Coup Pro-Democracy Alliance said in a statement.

The pro-Morsi group called on the marchers to set off from mosques in Cairo, with one of the largest rallies starting at Ramses Square, Al Jazeera's Rory Challands reports from Cairo.

As crowds gathered outside the security directorate in Fayoum, 28 pro-Morsi protesters and one police officer were injured when clashes broke out between the police and demonstrators, police said.

Reuters news agency later quoted security sources saying that the clashes had taken place between several hundred supporters and opponents of Morsi.

Some of the injured suffered the effects of teargas inhalation, while birdshot wounds were also reported by the health ministry.

In separate incidents in the Nile Delta province of Gharbiya, four people were injured in fights between pro-Morsi protesters and residents near an army base, state-run Al-Ahram newspaper said. Police arrested 13 Morsi-supporters, according to Reuters.

The 28 marches called by the Anti-Coup Pro-Democracy Alliance mostly passed peacefully and many demonstrators were in a celebratory mood, Challands reports.

The government said it held off from breaking up the protest camps in Cairo out of respect for the holy month of Ramadan, which ended Wednesday night, and to give foreign mediators an opportunity to find a peaceful solution.

But the Interim prime minister, Hazem al-Beblawi, warned late Thursday "that the situation is approaching the moment we would rather avoid."

"The government wants to give the protesters, especially the reasonable ones among them, a chance to reconcile and heed the voice of reason," he said, as protesters await a possible crackdown.

Pro-Morsi protesters had set up two protest camps in Cairo days before his overthrow on July 3 in a popularly backed military coup. They insist that they will disperse only when Morsi is reinstated.

"What will they do? Killing me, killing my kids, it doesn’t matter. Either we die as respectable people or we die," one protester told Al Jazeera.

More than 100 people, mostly Morsi loyalists, were killed in previous confrontations with police and soldiers.
