Two blasts in Afghanistan killed four civilians including a child, while at least 15 Taliban militants were killed in separate operations elsewhere in the country, officials said on Saturday, according to DPA. The blast was triggered by explosives attached to a parked bicycle in the western part of Kandahar city, the provincial capital of the same name, on Saturday morning as a police vehicle was passing by, said Mohammad Iqbal, a police official at the scene of the incident. The explosive that was detonated by a remote-controlled device killed a child and wounded two police officers and two civilians, he said. In a similar incident in south-eastern Paktia province on Saturday, three civilians were killed when their vehicle was blown up by a roadside mine, provincial spokesman Ghamai Khan Mohammadi said. He said that the bomb was newly planted on the road, which is often used by Afghan and international forces in the province.
