A grenade went off accidentally, wounding 24 soldiers at an army base in central Colombia, officials said.
The blast at the Tolemaida military base in Melgar town could have been an accident, armed forces commander Gen. Freddy Padilla de Leon said on Sunday.
"Nothing is clear yet, but the most probable theory is that it was an accident. There is a soldier who says he saw another soldier came out of the bathroom and dropped a grenade," Padilla de Leon said in Cartagena city.
The injured men belong to the Rapid Deployment Force Battalion that specialises in jungle fighting against guerrillas.
The wounded soldiers have been admitted to a hospital and investigators have been sent to the base to determine the causes of the explosion
