At least six people have been killed and seven injured after a Nato convoy was attacked just outside Pakistan's capital, Islamabad.
About 15 fighters fired machine guns and threw grenades before torching the trucks carrying military vehicles for Nato forces in Afghanistan early on Wednesday, Kalim Imam, a police officer, said.
Wednesday's strike - at a truck stop about 10km from Islamabad on the main road leading to the border with Afghanistan - was the first so close to Pakistan's well-protected capital.
Imam said six people were killed and seven wounded, but their identities were not yet known.
He said police were not aware that the truck stop was used by vehicles carrying supplies for Nato and US forces in Afghanistan.
Much of the supplies and fuel for the US-led force in landlocked Afghanistan are transported in trucks through Pakistan after arriving on ships docked at the Arabian Sea port of Karachi.
Thousands of trucks make the journey across the border each week, making it a lucrative business for truckers, but angering Pakistanis opposed to foreign involvement in Afghanistan.
Public execution
Fighters with bases along the remote Afghan border in Pakistan's northwest regularly attack government and security force targets.
On Tuesday, one such group, the Pakistani Taliban, staged a public execution in front of hundreds of tribesmen in North Waziristan, underscoring the level of control armed groups have there.
Pakistani officials say a Taliban-appointed court convicted a man of killing two others.
After the ruling, the Taliban reportedly paraded the man on a football field in Miran Shah before a brother of his alleged victims shot him.
