On Sunday, 13 people including a French engineer were killed by a twin bomb attack at a railway station east of Algiers.


Six soldiers were killed in the same province on Thursday when their convoy hit a bomb planted by anti-government fighters.


A day earlier, bombs killed two people near a military barracks in Bordj El Kiffan, about 25km east of the capital.


Up to 200,000 people have been killed in Algeria since 1992 after military-backed authorities scrapped parliamentary elections that an Islamist party was poised to win.
