A landmine explosion has left four children dead in the Dehrawood district in Afghan central Uruzgan province, an official said on Monday. The governor's spokesman Abdullah Himat told (Pajhwok) Afghan news agency that the explosion took place last evening, killing four children, aged between 6 and 8 years. The victims were playing in the area where the explosive device had been planted. He blamed militants for planting roadside bombs that often killed innocent civilians, including children. However, the Taliban have not yet commented on the incident. Landmine blasts have surged across the country, causing civilian casualties. Several people died in such incidents in Kunar Paktika, Logar and Nangarhar provinces.
