Two bombs exploded today at a railway station east of Algiers, killing twelve people including eight soldiers and two French engineers, security sources said.
The bombs went off at close intervals in the town of Beni Amrane in Boumerdes province, around 50 km (30 miles) from the capital, they said.
The soldiers were accompanying Frenchmen working for French water engineering company Razel when their convoy hit the bombs planted next to the station, according to one security source.
Another security source had said earlier that two people were killed.
There was no immediate claim of responsibility for the bombings, the third deadly attack in five days in the coastal region east of Algiers.
Six soldiers were killed in the same province on Thursday when their convoy hit a bomb planted by rebels.
A day earlier, bombs killed two people near a military barracks in Bordj El Kiffan, about 25 km (15 miles) east of the capital.
Al-Qaeda Organisation in the Islamic Maghreb has claimed responsibility for a string of bombings in the North African country including a twin attack on a court building and UN offices in Algiers in December in which 41 people were killed.
