MIRANSHAH (AFP) - Missiles fired from US drones Tuesday killed at least six militants in North Waziristan tribal district bordering Afghanistan, security officials said. US drones fired two missiles on a militant vehicle parked outside a compound. At least six militants were killed and three others were wounded, a senior security official told AFP. The compound, being frequented by militants recently, was also destroyed in the attack, he added. Another security official and two intelligence officials confirmed the missile strike and death toll. The official said it was not immediately clear whether any high value target was present at the time of the attack, which took place in the suburbs of Miranshah, the main town in the tribal district of North Waziristan. Residents said that the Taliban had started sifting through the debris and removing the bodies. The Taliban immediately cordoned off the area around the destroyed vehicle and the compound, a local tribesman told AFP on condition of anonymity. US drone attacks routinely target Taliban and Al-Qaeda commanders in countrys semi-autonomous tribal belt, which Washington calls the global headquarters of Al-Qaeda and the most dangerous region on Earth. A US drone strike in Miranshah in February had killed Mohammed Haqqani, a brother of Al-Qaeda-linked warlord Sirajuddin Haqqani, whose network is fighting against US and local forces in neighbouring Afghanistan. North Waziristan is increasingly the focus of the US drone war against Al-Qaeda and Taliban fighters active in Afghanistan. North Waziristans prominence in the covert drone war has grown since a Jordanian Al-Qaeda double agent blew himself up killing seven CIA employees in a neighbouring Afghan province in Dec. More than 830 people have been killed in more than 90 US strikes in Pakistan since August 2008, with a surge in the past year as US President Barack Obama puts Pakistan at the heart of his fight against Al-Qaeda.
