Tear gas and rubber bullets fired in Egyptian riots
Egyptian police have clashed with thousands of protesters demanding the resignation of President Hosni Mubarak in Cairo for a fourth consecutive day.
Protesters gathered after Friday prayers. Police used tear gas and water cannons to disperse the crowds, who responded by throwing stones.
At least seven people have died and up to 1,000 have been arrested since the protests began on Tuesday.
People also took to the streets in the coastal cities of Suez and Alexandria.
