The attack took place in the Khaider Khel area of Mir Ali district, 30 kilometres (18 miles) east of Miranshah, the capital of North Waziristan tribal region, on Monday when the US terror drone fired four missiles on a vehicle.
According to the security officials, several drones were flying in the area at the time of the strike.
Last week, Pakistani President Asif Ali Zardari in his speech to the United Nations General Assembly said that US assassination drone strikes are counter-productive and asked Washington to end the strikes on the country’s tribal areas.
Pakistani tribal regions are the target of US terror drones, with Washington claiming that its unmanned aircraft are targeting militants. However, casualty figures clearly indicate that Pakistani civilians are the main victims of the assaults.
The killing of Pakistani civilians, including women and children, in the strikes has strained relations between Islamabad and Washington, prompting Pakistani officials to send warnings to the US administration over the assaults.
Despite Pakistani government’s repeated calls on Washington to end the drone attacks, the US government continues its strikes on the tribal regions of the country.
The aerial attacks were initiated by former US President George W. Bush, but have escalated under President Barack Obama.
The drone strikes have triggered massive anti-US demonstrations across Pakistan to condemn the United States’ violations of their national sovereignty.
