MIRANSHAH: A US drone fired two missiles into a vehicle in Pakistan’s tribal district of North Waziristan on Friday, killing at least four militants, local security officials said.

The attack took place in Kharkamar area, 40 kilometres (25 miles) west of Miranshah, a stronghold of Taliban and Al-Qaeda linked militants.

“A US drone fired two missiles targeting a militant vehicle, killing at least four militants,” a senior security official told AFP.

It was the fourth such attack reported in Pakistan’s tribal badlands on the Afghan border, which Washington has dubbed the global headquarters of al-Qaeda, since US commandos killed Osama bin Laden in a Pakistani city on May 2.

The new attack coincided with a joint sitting of parliament in Islamabad, where Pakistan’s intelligence chief Ahmad Shuja Pasha and army chief of staff Ashfaq Kayani were briefing lawmakers on the bin Laden operation.
