MIRANSHAH, Pakistan -- A bomb attack has killed four Pakistani security personnel and wounded several in the North Waziristan region along the border with Afghanistan.
A security official told RFE/RL that a suicide bomber detonated his explosive vest near a paramilitary checkpoint.
The attack occurred on the road between Miranshah, the main town of the district, and the Ghulam Ali area.
Other reports said the explosion was caused by a roadside bomb that went off near a military truck.
Pakistan's northwestern tribal areas along the Afghan border are known hideouts of Taliban and Al-Qaeda militants.
