Separate roadside blasts in southern Afghanistan have killed 14 civilians, including three children, officials in the country said on Wednesday. Daud Ahmadi, a spokesman for the Helmand provincial government, said that 11 civilians were killed Wednesday after their van hit a bomb in the Gereshk district of the province. Ahmadi blamed the Taliban for planting the bomb. Mohammad Shah Khan, a police official, said that three children died after a bomb they found exploded while they were playing with it on a road west of Kandahar's capital. Taliban fighters regularly plant roadside bombs to attack Afghan and foreign troops but most victims of such attacks have been civilians.
