A senior police officer, Shaukat Ajmad, said assailants had opened fire on a car on Saturday, killing six people in Quetta, the capital of the impoverished south-western Baluchistan province.
Minutes later, they shot and killed two people in a rickshaw in the same area.
Although most Sunni and Shia Muslims live peacefully together, extremists have targeted Shi'a Muslims over the past three decades. In recent years, Wahhabis attacks on Shias have become far more common.
Ali Sher Haidry, spokesman for the banned extremist group, Lashkar-e-Jhangvi, Friday claimed responsibility for the recent attacks on Shiite Muslims in Quetta.
