Twenty-seven tankers were set on fire in a depot close to the capital Islamabad.

Police said six people were killed in the attack early on October 4 morning.

The Taliban in Pakistan claimed responsibility for the assault on the depot, as well as a previous incident in which a convoy was hit on October 1.

Pakistan is refusing to allow NATO convoys access to Afghanistan through the Khyber Pass in response to a NATO air-strike last week in which three Pakistani soldiers were killed.
