An Algerian security official says Algerian forces surrounded and killed four Islamist militants implicated in a roadside bomb attack a day earlier.
The official said the militants were shot dead Monday in the Beni Khelifa forest in the district of Boumerdes, some 30 miles (45 kilometers) from the capital of Algiers. One soldier died from the operation.
The official said security forces were alerted to the militants by villagers, speaking on condition of anonymity because they were not authorized to speak to the press.
On Sunday, a roadside bomb detonated near a military convoy in the area, killing four civilians and wounding 19.
