MANSEHRA, Pakistan (AP) — Gunmen wearing military uniforms stopped a bus in northern Pakistan on Tuesday, ordered selected passengers to get off and then killed 18 of them in an apparent sectarian attack, the police and a lawmaker said.
The victims were all Shiite Muslims, a minority in Pakistan that is frequently targeted by extremists from the majority Sunni community, said lawmaker Abdul Sattar.
A spokesman for a faction of the Pakistani Taliban, a Sunni militant group, claimed responsibility for the killings.
Around 27 other people on the bus were spared.
The incident in the remote Kohistan region was the latest in a spasm of violence in the country in recent weeks that has demonstrated the resilience of militant networks, including al-Qaida allied groups. The U.S. has tried to support Pakistani security forces in the fight against the extremists, but relations between the two nations are strained, hampering cooperation.
The attack took place in the mountainous village of Harban Nala, which is some 211 miles (340 kilometers) north of the capital Islamabad. The area, part of the famed Silk Road linking northern Pakistan to China, is populated by Sunni tribes.
Police officer Mohammad Azhar said the bus was traveling from Rawalpindi city to Gilgit when the gunmen attacked.
Sattar, the lawmaker, said eight gunmen were involved in the ambush, and all were wearing military uniforms, presumably to make it easier to stop the bus.
He said the attackers ordered the passengers to produce their identity cards before ordering the 18 off the bus and shooting them.
Haji Abdul Ghafoor, owner of restaurant in Mansehra where the bus stopped for dinner on Monday night, said there were around 45 people on board.
Sunni extremists allied to or inspired by al-Qaida and the Taliban routinely attack government and security force targets, as well as religious minorities and other Muslim sects they consider infidels. Most of the violence has been in the northwest, close to Afghanistan, though sectarian attacks happen across the country with some regularity.
Many thousands have been killed in the last five years, and attacks on Shiites — targeted purely because of their sect — have been some of the bloodiest.
The Jandullah faction of the Pakistani Taliban — one of the country's deadliest and best organized militant groups — claimed responsibility.
"They were Shiite infidels and our mujahedeen shot them dead one by one after bringing them down from a bus," said Ahmed Marwat, a purported commander, who called an Associated Press reporter from an undisclosed location.
