Unidentified gunmen opened fire on a vehicle in the southwestern Pakistani city of Quetta on January 6, wounding five people.
Police told RFE/RL's Radio Mashaal that the passengers, who were travelling in a taxi, were all members of the Shi'ite Hazara minority.
The five were taken to a nearby hospital, with two of them in critical condition.
Police said it was a targeted attack and the gunmen escaped from the scene.
No group has so far claimed responsibility for the attack, but the banned Lashkar-e-Jhangvi extremist group has been blamed for similar attacks in the past.
