Clashes have erupted between supporters and opponents of ousted Egyptian president, Mohamed Morsi, in the northeastern city of Zagazig, leaving at least eleven students injured.

The students were wounded during clashes which broke out at Zagazig University in the city, the capital of Ash Sharqiyah governorate, after supporters of Morsi including students staged a rally in support of the deposed president.

Similar clashes were also reported in Giza's Abu al-Nomros district, located in the west bank of the Nile River and about 20 kilometers southwest of the capital Cairo.

Moreover, on Sunday morning, students held a demonstration near Cairo University to demand Morsi’s reinstatement.

The demonstrators were carrying banners reading, “Where are you, freedom?” and “Free detainees.”

Since the ouster of Morsi, Egypt’s first democratically elected president, the country has been the scene of demonstrations held by his supporters.

On July 3, army chief Abdel Fattah al-Sisi announced that Morsi, a leading former member of the Muslim Brotherhood, was no longer in office and declared that the head of the Supreme Constitutional Court, Adly Mahmoud Mansour, had been appointed as the new interim president of Egypt. The army also suspended the constitution.

Hundreds of protesters, mostly Morsi’s supporters, were killed or wounded during the deadly violence that broke out afterwards.

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

Army officials said Morsi, who took office in June 2012, was being held “preventively” by the military.

After Morsi's ouster, Brotherhood supreme leader Mohamed Badie said the coup against him was illegal and millions would remain on the street until he is reinstated as president.
