A police official says gunmen have killed eight Shiite Muslims in southwestern Pakistan.

Operations police chief Aitzaz Goraya says the Shiites from the minority Hazara community were targeted outside the vegetable market in Quetta on Thursday morning.

He says four gunmen riding two motorcycles killed six men in a mini bus and chased another two down before shooting them dead. Another two people were wounded.

No one has claimed responsibility, and the officer said it was not clear who carried out the attack.

Suspicion likely is to fall on Sunni Muslim extremists, who have targeted Shiites in the past.
