Second day of clashes hits Cairo after football deaths
Protesters have gathered on the streets of Egypt's capital Cairo amid calls for more rallies over the deaths of 74 fans at a football match on Wednesday.
Sporadic clashes have already been reported in the city and large rallies are expected after Friday prayers.
Hundreds were injured in fighting between security forces and protesters across the country on Thursday.
Many Egyptians blame police for causing the football riot in the northern city of Port Said.
