Dozens die in Pakistan bus attack
Gunmen have killed more than 40 people on board a bus in southern Pakistan bound for a Shiite community centre.
The attack in the port city of Karachi was the deadliest Pakistan has seen in months. Provincial police chief Ghulam Haider Jamali said 43 people were killed, including 16 women, and another 13 people were wounded.
The bus was in a relatively deserted area on the outskirts of the city en route to a community centre for Ismaili Shiite Muslims when six gunmen boarded it and opened fire, Mr Jamali said. The attackers then fled on three motorcycles.
"These are the people who are extremists, who are terrorists," Mr Jamali said of the assailants. "These are the same people who have been doing terrorism before."
Qadir Baluch, a security guard at a nearby building, said he heard the gunshots and saw the militants driving away. He said one of them was wearing a police uniform.
Local TV showed the bus riddled with bullets and panicked relatives crying at the scene or waiting at the hospital.
A splinter faction of the Pakistani Taliban called Jundullah, or Army of God, claimed responsibility for the attack.
A man purporting to be a spokesman for the group said "infidels were the target". The purported spokesman, Ahmad Marwat, has conveyed similar claims in the past.
The Taliban and other Sunni Muslim militant groups have long had a presence in Karachi. Sunni extremists view Shiites as apostates and have targeted them in the past, though attacks on the Ismaili branch have been rare.
Qasim Shah, an Ismaili community member, said the bus service had been operating for the last 10 years.
"They were innocent people," said Qaim Ali Shah, the chief minister of Sindh province, of which Karachi is the capital. "We feel very sorry for this ghastly act."
The attack was the deadliest in Pakistan since December, when Taliban militants killed 150 people, mostly young students, at an army-run school in Peshawar.
The Pakistani Taliban have been fighting for more than a decade to overthrow the government and impose a harsh version of Islamic law. Their attacks have killed tens of thousands of people.
Pakistan launched a major military operation nearly a year ago in the North Waziristan tribal region along the Afghan border, where the Taliban and other militant groups had long found safe haven.
Pakistani army chief General Raheel Sharif cancelled a three-day visit to Sri Lanka after the attack. He and Prime Minister Nawaz Sharif visited Kabul on Tuesday, where they pledged to work with the Afghan government to fight militants.
Prime Minister Nawaz Sharif condemned the bus attack, calling it "an attempt to create chaos".
"Terrorists have chosen a very peaceful and patriotic community to target in order to achieve their nefarious designs," he said.
Later, the death toll was increased to 45.
