Clashes broke out between supporters and opponents of ousted president Mohammad Mursi in the Cairo neighborhood of Shubra on Friday, witnesses said.

"The clashes erupted early in the afternoon," the witnesses added.

Live footage on satellite station ONTV showed crowds throwing rocks at each other in the neighborhood.

Mursi's supporters and backers of the military that overthrew him on July 3 are both staging rival rallies across Egypt.

Witnesses said the clashes in Cairo began after Mursi's opponents, who rallied at the behest of the military, burned posters of the ousted Islamist leader.
