ISLAMABAD — Suspected militants attacked and set fire to at least 20 tankers carrying oil for NATO and U.S. troops in Afghanistan on Monday, the third such strike inside Pakistan in as many days, police said.
The attack not far from the capital Islamabad took place on a supply line that has been stalled because of a temporary border closing imposed by Pakistani authorities to protest a NATO helicopter attack that killed three Pakistani troops last week.
It will raise the stakes in the closure, which has exacerbated tensions between Washington and Islamabad but has been welcomed by Islamist groups opposed to Pakistan's support of the U.S.-led war in Afghanistan.
Police officer Umer Hayat said three people were killed and blamed Monday's attack on terrorists.
The attackers opened fire on trucks that were parked at a poorly guarded terminal before setting them afire, he and other officers said.
The trucks were en route or waiting to travel to the Torkham border crossing along the fabled Khyber Pass, which is used to bring fuel, military vehicles, spare parts, clothing and other non-lethal supplies for foreign troops in Afghanistan. Pakistan's other main route into landlocked Afghanistan, in Chaman in the southwest, has remained open.
While NATO and the United States have alternative supply routes into Afghanistan, the Pakistani ones are the cheapest and most convenient. Most of the coalition's nonlethal supplies are transported over Pakistani soil after being unloaded at docks in Karachi, a port city in the south.
