Two bombs exploded Sunday at a train station in Algeria, killing 13 people and injuring several others, a security official in the North African nation said.
Both bombs at the station in Beni Amrane, just over 100km east of the capital, were apparently triggered by remote control, the official said.
The first bomb killed at least two of the victims, including a French citizen working on a project to repair the station's rails. He was targeted as he left the work site by car, the security official said. His Algerian driver was also killed.
A second bomb minutes later was apparently timed to explode as security forces and rescue workers arrived at the scene, said the security official, who spoke on condition of anonymity because he was not authorised to speak to media.
Though the overall death toll was 13, it was unclear exactly how many people were killed in each attack, he said. Several other people were wounded.
There was no immediate claim of responsibility. Algeria's al-Qaida affiliate, al-Qaida in Islamic North Africa, is known to be active in the area.
The North African nation's Islamic militants have mounted increasing attacks over the past two years. On Wednesday, a suicide attack on a military barracks and a second bombing at a cafe shook a beach neighbourhood outside the Algerian capital Wednesday, wounding six people. On Thursday, a roadside bomb killed six soldiers in the city of Boumerdes.
