Supporters of Egypt's deposed president Mohamed Morsi staged mass marches in several Egyptian governorates Monday night, following a call for protests by an Islamist alliance led by the Muslim Brotherhood – from which Morsi hails – to demand his reinstatement.

Marches were reported in the cities of Alexandria, Luxor, Damanhour and Suez decrying the popularly-backed military overthrow of Morsi on 3 July.

The Muslim Brotherhood has strongly rejected the "blatant coup d'etat" against Morsi, elected in June 2012, and demanded his return to power.

Meanwhile, clashes erupted in Cairo on Monday evening after police forces used teargas to disperse a crowd of Morsi's supporters who gathered in downtown's Ramsis Square, as tens of thousands remain in a sit-in several kilmetres away in Rabaa Al-Adawiya Square.
