ALGIERS, Jan. 9 (Xinhua) -- At least ten suspected terrorists were killed Saturday night in northeastern Algeria, the official Algerian news agency APS cited a security source as reporting.

These armed suspects were taking a utility vehicle in Slim, western part of northeastern Algerian province of M'sila, as they were caught in an ambush by the security forces acting on a tip-off, according to the source.

The source added that an "important quantity" of weapons have been seized during the operation.

In December, Algerian security forces killed four armed extremists in the same province.
