Seoul: North and South Korean troops exchanged fire along their tense border on Sunday, the South's military said, the first such incident since the rivals took unprecedented steps to lower front-line animosities in late 2018.
Violent confrontations have occasionally occurred along the border, the world's most heavily fortified. While Sunday's incident is a reminder of persistent tensions, it didn't cause any known casualties on either side and is unlikely to escalate, observers say.
The Joint Chiefs of Staff in Seoul said in a statement that North Korean troops fired several bullets at a South Korean guard post inside the border zone. South Korea responded with two rounds after issuing a warning broadcast, it said.
South Korea suffered no casualties, the military said. It's unknown whether North Korea had any. The North's official Korean Central News Agency hasn't reported about the incident.
South Korea said it was trying to contact North Korea via a military hotline to avoid an escalation.
It comes a day after North Korea broadcast images of leader Kim Jong Un reappearing in public after a 20-day absence amid intense speculation about his health.
KCNA said Kim attended Friday's ceremony marking the completion of a fertilizer factory near Pyongyang along with senior officials. State TV showed Kim smiling and walking around factory facilities.
Kim earlier vanished from the public eye after presiding over a Politburo meeting of the ruling Workers' Party on April 11 to discuss the coronavirus. Speculation about his health began swirling after he missed an April 15 event commemorating the birthday of his grandfather and state founder, Kim Il Sung, something he had never done since inheriting power upon his father Kim Jong Il's death in late 2011.
The Koreas are split along the 248-kilometer -long, 4-kilometer-wide border called the Demilitarized Zone that was originally created as a buffer after the end of the 1950-53 Korean War. But unlike its name, an estimated 2 million mines are peppered inside and near the DMZ, which is also guarded by barbed wire fences, tank traps and combat troops on both sides.
In late 2018, the two Koreas destroyed some of their front-line guard posts and began removing mines from the DMZ as part of steps to reduce tensions. But the efforts stalled amid a deadlock in nuclear negotiations between Kim and President Donald Trump meant to convince North Korea to give up its arsenal. The diplomacy hasn't made any headway since the second Kim-Trump summit in Vietnam in early 2019 broke down due to disputes over U.S.-led sanctions on North Korea.
Earlier this year, North Korea carried out a slew of missile and other weapons tests, but they were short-range and none posed a direct threat to the U.S. mainland.
The last time there was gunfire along the Korea border was in November 2017, when North Korean soldiers sprayed bullets at a colleague fleeing to South Korea. The defector was hit five times, but survived and is now living in South Korea. South Korea at the time didn't return fire.
Previously, the two Koreas traded gunfire along the DMZ numerous times, but no deadly clashes have occurred in recent years. A 2015 land mine blast that maimed two South Korean soldiers still pushed the Koreas to the brink of an armed conflict. South Korea blamed North Korea for the explosion.
