At least Six Pakistani border guards were killed Monday and another two were wounded in explosion of a roadside bomb in Baluchistan province in southwestern Pakistan.

The explosion happened when a Frontier Corps patrol was passing by, Fox News quoted the Spokesman of the Pakistani forces as saying.

No actor claimed its responsibility for the explosion.

A suicide bomber rammed his motorcycle into an army truck in Baluchistan on Saturday, killing 15 people and wounding more than 30.
