South Korea's military is keeping its full combat readiness against North Korea's possible provocations as the North's soldiers are preparing for their monthslong winter training, the South's military said Monday.
Seo said that at around 3:14 p.m. on Monday, the JCS spotted three North Korean soldiers moving south of the Panmungak, or the North's main building in the Joint Security Area.
The soldier was being operated upon for a second time on Wednesday, the hospital treating him said.
