Thousands of people in Egypt have taken to the streets to protest against their president.
The protesters have clashed with the police, who have used tear gas and water cannons to try to break up the crowds.
At least seven people have died and up to 1,000 have been arrested since the demonstrations began on Tuesday.
The internet and mobile phone access has cut off as protests went into a fourth day.
Lots of people in Egypt are very poor - many think that President Hosni Mubarak is treating them badly and not doing enough to make their lives better.
President Mubarak of Egypt
He's been ruling the country for 30 years but protesters want him to step down.
Demonstrations this size are very unusual for the country and everyone's watching to see what will happen next.
