There have been violent clashes in Cairo and three other Egyptian cities between police and university students loyal to the ousted Islamist president.
In the capital pitched battles went on for hours as the students from Ein Shams university pelted police with rocks. The security forces used tear gas to try to disperse the protesters.

Clashes also broke out in the Mediterranean city of Alexandria and in Mansoura, north of Cairo.
