Security forces have intervened after the supporters and opponents of Egypt's ousted president, Mohamed Morsi, clashed in the city of Mansoura, Dakahlia Governorate.

The clashes erupted on Tuesday as the two sides, who were holding separate rallies at al-Mansoura University, got engaged in hurling stones at rival protesters.

Riot police stepped in and fired tear gas to disperse the crowd.

There were no immediate reports on the number of possible casualties.

Tensions have been running high in Egypt since the ouster of Morsi, Egypt’s first democratically elected president, by the country’s powerful military in July.

The army suspended the constitution, dissolved the parliament and declared the head of the Supreme Constitutional Court, Adly Mahmoud Mansour, as the country’s interim president.

This triggered mass street rallies, spearheaded by the Egyptian Muslim Brotherhood - protests which were invariably met with use of violent force by the army-backed interim government.

Egyptian security forces have arrested more than 2,000 Muslim Brotherhood members, including the party’s leader, Mohamed Badie, who was detained on August 20.

About 1,000 people were killed in a week of violence between Morsi supporters and security forces after police dispersed their protest camps in a deadly operation on August 14.

The massacre sparked international condemnation and prompted world bodies to call for an independent investigation into the violence.
