Three more killed in separate attack in Sinai - sources

CAIRO (Reuters) - Three more members of Egypt's security forces were killed in an attack in a town in the Sinai Peninsula on Friday, hours after a car bombing claimed 25 lives, security sources said. Men opened fire at the security forces at a checkpoint in the town of al-Arish, they said. It was not immediately clear whether the dead were soldiers or police.
