Gunmen on motorcycles shot dead eight people, including an eight-year-old girl, at a faith healer's house in the Pakistani port city of Karachi, police and doctors have said.

At least 12 others were also wounded in the shooting on Sunday in Baldia Town, as dozens of people waited for their turn to see Pir Meharban Shah. 

"Six gunmen on three motorcycles stormed into the house and started indiscriminate firing," senior police official Irfan Baloch told AFP news agency.

"At least eight people were killed and 12 others were wounded," Baloch said, adding that the dead included an eight-year-old girl and her father. The assailants fired 9mm pistols, a weapon used in a spate of targeted killings in the city, he added.

Shah, who provides spiritual healing services, received a bullet wound to his abdomen and said he had not received any threats prior to the attack.

No group has yet claimed responsibility for the attack.

Dr Aftab Chanarh, at Karachi's state-run Civil Hospital, confirmed the casualties.
