(Xinhua) -- At least 6 people were killed when a security forces gunship helicopter fired at a vehicle in Pakistan's North Waziristan tribal region on Thursday, a local TV channel DAWN NEWS reported. The vehicle was completely destroyed near Mir Ali in the firing, a major town in North Waziristan. The security forces also fired at two vehicles in the same area on Wednesday, but no one was injured, according to a report of News Network International (NNI) news agency. Unidentified militants blew up a gate along the border between Pakistan and Afghanistan, while some other militants also fired nine rockets at the Miranshah Airport, an army camp and a fort of paramilitary forces in North Waziristan on Wednesday night.
The law and order situation in the northwestern tribal areas worsened after local militants scrapped a peace agreement with the government and threatened to launch more attacks on security forces in mid-July. Clashes between militants and security forces occurred on a frequent basis in the area, resulting in heavy casualties.
