Militant opened fire on a bus carrying Muslim Shiite in southwest Pakistan on Tuesday, killing 13 passengers.

The attack took place on the outskirts of Quetta, the capital of oil and gas-rich Balochistan, which borders Iran and Afghanistan.
"Four gunmen riding two motorcycles opened fire on a bus in the outskirts of Quetta," local police official Hamid Shakeel told AFP.

"The death toll has risen to 13. Two of the injured who were in critical condition died in hospital. Now 12 Shiite Muslims and one Pashtun have been killed in the attack," he said after initially putting the death toll at 10.
The passengers were members of Pakistan's minority Hazara ethnic group and had been travelling from the Hazara-dominated town of Hazarganji to Quetta.

Television footage showed the bus engulfed in flames, with blood and passengers' luggage seen scattered at the site sealed off by a paramilitary and police cordon.
