Seven Injured as Grenade Explodes on S.Korean Vessel During Naval Drills

A grenade exploded on the South Korean Navy’s Chamsuri-class patrol boat while they were conducting a maritime firing drill off the southern coast on Tuesday.

Seven sailors were injured in the incident that occurred around 12.20pm on the 130-ton boat affiliated with the Third Fleet in waters near Geoje Island, the Navy said in a statement.

"The Navy immediately halted all firing drills on and off shore, and is conducting an investigation into what caused the accident. We will then seek preventive measures," the military said.

Around 30 sailors were on the patrol boat at the time of the accident for a drill "necessary for the maintenance of the vessel and readiness posture," a naval officer was quoted as saying by Yonhap.
