Security forces shot dead a Bedouin protester in the north of Egypt's Sinai region on Thursday, eyewitnesses and a security source said.
The 22-year-old man, Mohamed Atef, was shot in the head while demonstrating in the town of Sheikh Zoweid, they said. Security forces fired tear gas to disperse dozens of protesters.
The shooting came as police fought protesters in Suez and Ismailia, two cities straddling the Suez Canal that separates Sinai from the rest of Egypt.
Bedouin, among nomadic tribes in Egypt's northeast Sinai region, often complain of neglect by the government and of police harassment.
Protests in the country entered their third day on Thursday. Activists trying to oust President Hosni Mubarak set fire to buildings in the eastern city of Suez and played cat-and-mouse with police, while prominent reform campaigner Mohamed ElBaradei called on Mubarak to leave office after 30 years.
Egyptians torched a police post in the eastern city of Suez early on Thursday in response to the killing of three demonstrators earlier in the week, a Reuters witness said. Police fled the post before the protesters burned it using petrol bombs.
One policeman has been killed in Cairo in the clashes, which erupted on Tuesday, inspired by a popular revolt in Tunisia.
Protesters complain about surging prices, a lack of jobs and authoritarian rule that has relied on heavy-handed security to keep dissenting voices quiet.
