Officials: Bomb attack kills 14 in Pakistan From Reza Sayah, CNN June 16, 2012 -- Updated 0801 GMT (1601 HKT) At least 26 others are injured, officials say The blast occurs near a market in Khyber district Khyber is one of seven districts in Pakistan's largely lawless tribal region Islamabad, Pakistan (CNN) -- A bomb exploded near a market in northwest Pakistan on Saturday, killing at least 14 people and leaving 26 injured, authorities said. The bomb was in a truck in Landi Kotal town in Khyber, a district in Pakistan's tribal region, according to local officials, Arshad Khan and Gulam Faruq. It targeted members of Zakha Khel tribe, a pro-government group locked in a bloody turf war with militant group Lashkar-e-Islam. For years, the militant group has fought for dominance in the district by taking on both the Pakistani Taliban and government forces. Khyber is one of seven districts in Pakistan's mostly ungoverned tribal region along the Afghan border. The area has been plagued by a mixture of sectarian and gang violence, as well as the government's fight to take on the region's Islamist militants. One of NATO's main supply routes in Pakistan went through Khyber until the Pakistani government shut it down last year in protest over a NATO strike that unintentionally killed 24 Pakistani soldiers.
