Ali Madad Jatak, a former Pakistan People's Party provincial minister, who was inside the mosque at the time, said he believes he was the target of the attack that also injured 20 people, the BBC reported.
"They fled after killing innocent people," Jatak said of the four gunmen. "I was the target. They could have fired at me. They killed innocent worshippers belonging to different communities. This is against humanity. It is brutality on the level of animals."
No one claimed responsibility for the attack, but a Baloch separatist insurgency has committed recent attacks in Quetta, the capital of Balochistan province, Dawn News reported. There also has been sectarian violence in the province between Sunnis and Shiites, the BBC said.
