Colombia ( 3 children died after an explosion on an army training area )

Three children have died after an explosion on an army training area in the eastern Colombian state of Vichada.
The children aged 7, 9 and 13, had strayed into the training area about 3pm on Wednesday, while tending to their cow herd, said military authorities.
The army said the range had not been used in a month and they are investigating whether the explosion came from unexploded ordnance or planted explosives.
Three other children were injured and one was air-lifted to an Air Force hospital in Villavicencio.
