One Army soldier was killed and six others were injured Friday in an explosion during an artillery firing drill, the military said.
The blast occurred on the shooting range of a front-line Army unit in Cheorwon, some 88 kilometers north of Seoul, at 3:19 p.m., according to an Army officer.
Seven servicemen were rushed to a hospital and one of them, a 27-year-old sergeant first class, died during the transport, the officer said.
"An unidentified explosion took place during the drill, injuring some people," he said. A probe into the cause of the incident is underway, he added.
Flames erupted from inside one of the 10 K-9 Thunder self-propelled howitzers during the training session, injuring the seven soldiers attending it, according to the officer. (Yonhap)
