University students and non - governmental organizations(NGOs) in Iran have taken to street to condemn Egyptian police ' s heavy - handed treatment to suppress pro - Morsi supporters.

Hundreds of students as well as members of various NGOs gathered outside Egypt’s interests section in Tehran on Thursday, chanting slogans in condemnation of Egyptian police brutality against civilians.

They also demanded an immediate cessation of the violence in Egypt, and called for a probe into Egyptian security forces ' deadly clampdown on demonstrators.

Tensions have intensified in Egypt since July 3, when the country’s powerful military deposed former president, Mohamed Morsi, suspended the constitution, and dissolved the parliament.

On Wednesday, Egyptian security forces moved in to clear out thousands of supporters of the ousted president from two camps - one near the Rabaah al - Adawiya Mosque in Cairo’s Nasr City and a smaller one in Nahda Square in Giza.

Egypt’s Health Ministry says at least 525 people were killed and 3,600 injured in Wednesday’s violence.

Over 43 security personnel, including a number of generals and colonels, were among the dead.

However, the Muslim Brotherhood put the death toll far higher, saying more than 2,000 people had died. It has vowed to peacefully defeat the military coup that led to Morsi’s ouster last month.
