Demonstrators angered by the deaths of 74 people after a football match in the city of Port Said on Wednesday have clashed with police outside the Egyptian interior ministry in Cairo.

Police fired tear gas to stop protesters getting near the ministry.

The government has declared three days of mourning, sacked a wave of officials and launched an investigation.

Funerals of some of the victims have taken place in Port Said.

The BBC's Rupert Wingfield-Hayes describes an atmosphere of "anger, disbelief and suspicion" from Cairo.
