Protests broke out once again in Cairo on the anniversary of the overthrowing of former president Hosni Mubarak.

Groups opposing his successor, President Mohammed Mursi, clashed with riot police in the Egyptian capital, two years after Mubarak was pushed out of power on 11 February, 2011.

Police reportedly used tear gas and water cannon to disperse crowds of demonstrators that had gathered outside the presidential palace.

Critics of Mursi are angered by the new president’s autocratic rule, amid claims he forced through a constitution that fails to protect freedom of expression and worsening the Egyptian economy.The recent protests follow rioting in Port Said and two other major cities close to the Suez Canal in late January.

Riots broke out after a court sentenced 21 people to death for their role in last year’s riots at the Port Said football stadium.
