ISMAILIA, Egypt (Reuters) - Five people died and 42 were wounded in clashes between Egyptian protesters and police in the north Sinai town of el-Arish on Friday, witnesses said. Hundreds of people attacked the main police station using petrol bombs in the Mediterranean town near the border with Gaza in an attempt to free prisoners, before it was announced that President Hosni Mubarak had stepped down. Three of those who died were policemen. Police evacuated the building, which was partly destroyed by fire, and prisoners managed to escape. Five police vehicles were set on fire.
