At least 16 people were killed in an attack in Pakistan on a truck carrying fuel supplies for NATO forces in Afghanistan.
The victims had gathered to collect oil from the tanker, which was already ablaze following a blast late last night.
They were killed in a second bomb attack on the truck.
A militant group affiliated with Pakistani Taliban claimed responsibility for the attack.
It is the latest attack in an upsurge in violence since Osama bin Laden was killed.
The blast took place near the Torkham border crossing in the Khyber region, the main route for moving supplies to NATO and US forces in Afghanistan.
Police officials said the first blast was caused by a bomb.
In another attack in the same region, a bomb struck 16 NATO fuel trucks late yesterday, setting them on fire. No one was hurt.
Militants have stepped up attacks in Pakistan since US special forces killed al-Qaeda leader Bin Laden in the garrison town of Abbottabad this month.
Militant group Abdullah Azzam Brigade said it was their 'jihad against Americans.'
'We want to stop supplies for NATO from our territory,' Abu Musa'ab, a spokesman for the group, said.
The attacks on the NATO trucks in Khyber came hours after the Pakistani Taliban claimed responsibility for a bomb attack on a US consulate convoy in the city of Peshawar.
One Pakistani was killed and 12 people were injured, including two lightly wounded US nationals.
Routes through Pakistan bring in 40% of supplies for NATO forces in Afghanistan, according to the US Transportation Command.
Of the remainder, 40% come through Afghanistan's neighbours in the north and 20% by air.
The Pakistani Taliban are pressing ahead with their campaign of suicide bombings designed to de-stabilise the unpopular government, despite several army offensives against their strongholds along the lawless border region with Afghanistan.
