At least nine people were killed when gunmen opened fire outside a mosque in the second attack in Quetta in south-west Pakistan in as many days.
About 20 others were wounded in the attack, which came as worshippers left the Sunni Muslim mosque after sunrise prayers for the Eid al-Fitr festival.
Bullets hit the car of Ali Madad Jatak, a former Pakistan People's Party provincial minister, but he was unhurt.
On Thursday dozens of people died in a suicide bomb blast in Quetta.
In the latest attack, four unidentified men opened fire on the former minister as prayers came to a close.
