Hundreds of demonstrators gathered in front of the presidential palace in Heliopolis Monday night and clashed with security forces posted outside the palace gates.
The crowd was protesting against President Mohamed Morsi, many calling for his departure. Some used the familiar green-coloured lasers to identify security forces posted on the palace roof.
Masked protesters attempted to remove the barbed wire securing the palace gates, prompting security forces to disperse them with water canons. Protesters responded by throwing rocks at the gates and policemen operating the water cannons.
Calm was stored after hours of clashes.
