Two bombs exploded Sunday at a train station in Algeria, killing 13 people and wounding several others, a security official said.

Both bombs at the station in Beni Amrane, about 60 miles east of the North African nation's capital, were apparently triggered by remote control, the official said.

The first bomb killed at least two people, including a French citizen working on a project to repair the station's rails. He was leaving the site in a 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 authorized 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.

Islamic militants in the country have mounted increasing attacks over the past two years. A suicide attack on a military barracks and a second bombing at a cafe shook a beach neighborhood outside the Algerian capital of Algiers on Wednesday, wounding six people. On Thursday, a roadside bomb killed six soldiers in the city of Boumerdes.
