A US unmanned aircraft fired two missiles at a vehicle in Pakistan's restive South Waziristan tribal district on Saturday, killing at least three people, a government official said, DPA reported.
It was the second drone attack in less than 72 hours targeting suspected militants in the Sheen Warsak area, located close to the district's main town of Wana, said senior administration official Shahid Ali.
Another official, speaking on condition of anonymity, said al-Qaeda operative Abdul Rehman al-Zaman Yemeni was among the dead. It is hard to verify the information independently because media have limited access to the region bordering Afghanistan.
A similar drone attack on a house Thursday had killed two people, including al-Qaeda-linked militant Sheikh Abdul Bari.
Pakistan has continuously opposed the US drone campaign, saying it violates its sovereignty and antagonizes the local population which hurts Islamabad's own efforts to fight insurgency.
