At least 20 people have been killed after a bomb tore through a vegetable market in southwestern Pakistan early Friday morning, according to the New York Times. A senior police official told the newspaper that the bomb was hidden inside a sack of potatoes. Shopkeepers and customers were reportedly among the victims, as was a paramilitary soldier. The tragedy occurred in Quetta which has been the site of numerous attacks by Sunni extremists against Hazaras people, who are a Shiite Muslim minority in the region. The militant group Lashkar-e-Jhangvi, which has previously been active in the area, claimed responsibility for the attack.
