SEOUL—North and South Korea exchanged gunfire after multiple bullets from the north hit a guard post on the South Korean side of the demilitarized zone early on Sunday, raising tension a day after North Korean leader Kim Jong Un ended an almost three-week absence from public life with state media showing him visiting a factory.
The gunshots were fired from North Korea at 7:41 a.m. local time, the South’s joint chiefs of staffs (JCS) said in a statement. The South fired back with two shots following a broadcast warning of the action.
