At least 19 people, including women and children, were killed when their bus hit a roadside mine in Afghanistan Wednesday, said Daud Ahmadi, a spokesman for the governor of Helmand province, quoted by CNN. Their bus was traveling from provincial capital Lashkar Gah to Sangin district in the south of the restive province, he said. He said he did not know whether the civilians were the target of the roadside mine planted by the Taliban.
