Islamabad, Pakistan (CNN) -- Militants killed a driver of a container truck carrying supplies for NATO in Pakistan's tribal region on Monday, a government official told CNN. Three gunmen in a car opened fire on the truck in the Jamrud area of Khyber Agency, a district in Pakistan's tribal region bordering Afghanistan, said Bakhtiyar Khan, a government official in the district. Khan said three members of the truck crew were also injured in the incident as the vehicle moved towards the Pakistan-Afghanistan border. There was no immediate claim of responsibility for the attack. Several anti-American militant groups, including the Taliban, are active in the region.
