Defiant Morsi supporters march in Cairo

Supporters of Egypt's deposed president Mohamed Morsi are continuing to stage 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 marches to begin after Friday afternoon prayers as the nation rested on the second day of the Eid al-Fitr holiday. Al Jazeera's Rory Challands reports from Cairo.
