A US drone strike in Pakistan's northwestern tribal belt along the Afghan border on Wednesday killed at least seven fighters of the militant Haqqani network, local security officials said. A US drone fired two missiles, destroying a vehicle and a compound near Miranshah, the main town in North Waziristan tribal district. Three other militants were wounded in the strike, the officials said. "At least seven militants were killed in the drone strike. All of them were Haqqani's men," a Pakistani security official in Miranshah told AFP. Another security official at Peshawar confirmed the attack and casualties and added that three militants were also wounded. The Haqqani network is considered the most dangerous enemy of US troops in eastern Afghanistan. It was founded by Jalaluddin Haqqani and is run by his son, Sirajuddin, both of them designed "global terrorists" by Washington. The network has been blamed for some of the deadliest anti-US attacks in Afghanistan, including a suicide attack at a US base in the eastern province of Khost in 2009 that killed seven CIA operatives.
