Unknown gunmen attacked NATO oil supply tankers early Monday in Khairpur, wounding three people and destroying 10 vehicles, police said.
The tankers were attacked when the drivers and crew were having tea at a roadside restaurant.
“Two drivers and a member of the restaurant staff were wounded and 10 NATO oil tankers were burnt when about two dozen armed gunmen opened fire at them,” said local police official Mohammad Hashim.
Hashim said that it was too early to say who could be behind the attack, but Taliban and Al-Qaeda-linked militants frequently launch such attacks across Pakistan and the lawless tribal belt on the Afghan border.
He said no group had yet claimed responsibility for the attack.
Local government and intelligence officials confirmed the attack.
Most supplies and equipment required by foreign troops in Afghanistan are transported through Pakistan.
