The two policemen were on Eid duty when two gunmen on a motorcycle opened fire on them on Saryab road.
SP Zahoor Afridi said the assailants had opened indiscriminate firing on the police mobile in which constable Faiz Muhammad and driver Nameed were killed on the spot.
No group claimed responsibility for the killings. This is not the first time security personnel particularly policemen have been targeted by gunmen in Quetta and in recent months there have been a spate of target killings.
Only last week a policeman was shot dead inside a mosque near Galwamdni area.
