One protester has died and dozens have been wounded in violent anti-government clashes with police in the Nile Delta province of Dakahliya, according to Egypt's Interior Ministry.
Activists say Hossam Eldin Abdullah Abdelazim died after an armoured police vehicle crushed him to death during the clashes.
The fighting erupted overnight and continued for several hours before dawn on Friday in the city of Mansoura, where about 400 people protested outside a local council office.
The ministry said protesters were chanting anti-government slogans before they cut off a main road and threw firebombs at the building.
Residents in Dakahliya are calling for a civil disobedience campaign similar to one in Suez Canal cities.
