A roadside bomb ripped through a car in southern Afghanistan, the deadliest of a series of weekend attacks that killed 11 civilians, officials said Sunday. According to AP, seven people, including three women and two children, were killed and eight others wounded when the car was hit while traveling in the volatile Helmand province, according to a statement by the provincial governor's office. It said the car was one of two carrying civilians between the districts of Musa Qala and Nawzad. It hit the bomb in Musa Qala. The statement said two other civilians were killed Saturday in a bombing in the Kajaki district, providing no other details. Insurgents also attacked a checkpoint elsewhere in the district, killing an Afghan policeman, it said. The statement said: "Taliban militants regularly plant roadside bombs to target Afghan and NATO forces, but the devices often kill Afghan civilians."
