CAIRO - Hundreds of supporters and opponents of Egyptian President Mohamed Mursi clashed in two cities north of Cairo on Wednesday, throwing rocks and causing numerous injuries, security sources said.
Cars and buildings were also damaged in the cities of Mansoura and Tanta. One source and some local media reported one person was killed but that could not be immediately confirmed.
Mursi is due to make a keynote speech in Cairo in a few hours to address calls for his resignation. Major opposition rallies are planned for the weekend, which some fear could turn violent.
