Pakistani militants attack NATO oil tankers

Militants in Pakistan have destroyed at least 40 tankers carrying fuel for the North Atlantic Treaty Organisation (NATO) in two separate attacks.



The first attack was at a depot near Quetta, while the second set ablaze a convoy in Nowshera, in the north-west.



Attacks on tankers have soared since Pakistan shut one of the main routes into Afghanistan over the deaths of several soldiers in a NATO raid.



The US and NATO have apologised for the helicopter attack last week, which killed at least two Pakistani soldiers.



NATO has admitted that two of its helicopters entered Pakistan on September 30 and killed two border guards, mistaking them for militants after they fired shots.



Pakistan says three soldiers were killed.



The attack infuriated public opinion in Pakistan and led to anti-NATO demonstrations.
