Gunmen in Pakistan opened fire on oil trucks bound for NATO forces in Afghanistan, setting some 20 vehicles on fire and killing three, police said Monday.
The attack came shortly after Pakistan's ambassador to the United States vowed his country would go after terrorists on its soil.
Naeem Iqbal, a police spokesman, said five people were wounded in the attack on tankers parked on a main road outside a housing complex near the capital city of Islamabad. Efforts to put out the blaze are ongoing, he said.
Bin Yamin, a deputy police chief, said eight gunmen entered the area on Monday around 12:15 a.m. local time. He said they told people near the trucks to run away and that most did. Then they opened fire.
The tankers were parked in the vicinity of an oil refinery where they were going to go to pick up fuel for NATO forces in Afghanistan, Yamin said.
