SEOUL – The powerful sister of North Korean leader Kim Jong Un on Wednesday rejected South Korean findings that North Korea planted land mines that injured three South Korean soldiers last week and threatened to retaliate if the South fires on North Korean troops fortifying the border.
The incident could further inflame tensions between the Koreas, which have no working military hotlines or other emergency communications channels as North Korea hardens its stance toward Seoul while expanding its military nuclear program.

Three South Korean soldiers were injured in two explosions on Sept. 21 near the military demarcation line in the western section of the Demilitarized Zone, a heavily fortified border buffer zone between the Koreas that’s commonly known as the DMZ.
The statement by Kim Yo Jong came after South Korea’s military on Monday announced a preliminary assessment that the blasts were caused by North Korean mines following a joint inspection of the site with the U.S.-led United Nations Command.
UN Command says North Korea violated armistice agreement
The South Korean joint chiefs said South Korean and U.N. investigators discovered another North Korean mine Tuesday during a follow-up inspection. The U.N. Command said Wednesday that North Korea had violated the armistice agreement that ended fighting in the 1950-53 Korean War. The agreement prohibits both sides from committing any hostile act “within, from, or against” the DMZ and bans military or civilian personnel from crossing the military demarcation line without authorization from the armistice commission.
The U.N. Command said it was addressing the violation through established mechanisms but didn’t elaborate.
Kang Hyunwoo, the South Korean Joint Chiefs of Staff’s director of operations, said the military “strongly urges” North Korea to apologize for the blasts and take “responsible measures” to prevent a recurrence. South Korean Defense Minister Kang Shin-chul said the South would consider unspecified “corresponding measures” if a complete investigation confirms the North was responsible.
Kim calls Seoul’s claims a ‘farce’
Kim Yo Jong, who is considered possibly the second most powerful figure in Pyongyang, called the South Korean assessment a “conspiratorial farce,” accusing Seoul of making groundless claims to create a pretext for provocation against the North.
North Korea in recent years has added mines, anti-tank barriers and other front-line fortifications, raising concerns in the South about the growing presence of North Korean soldiers near the border. Kim criticized the South for broadcasting warnings and firing warning shots at North Korean troops conducting front-line fortification work, insisting “our soldiers have never crossed the border.”
“If the (South Korean) military gangsters fire at our soldiers carrying on the permanent project for the southern border, not warning shots, our border units will take immediate and merciless retaliatory action,” she said.
The recent explosions, which took place about 10 meters (yards) south of the military demarcation line, came during an operation to establish a patrol route through a densely vegetated area. The route was intended to allow future inspections with the U.N. Command after South Korea since last year detected “terrain changes” that may have resulted from North Korean minelaying.
The DMZ is a 248-kilometer (155-mile) strip and one of the world’s most heavily fortified borders, with an estimated 2 million land mines, barbed-wire fences, tank traps and combat troops on both sides.
In August 2015, another spate of land mine blasts that maimed two South Korean soldiers and sharply raised tensions between the Koreas.
The Koreas then traded threats, staged weapons demonstrations and resumed border propaganda broadcasts before days of marathon talks eventually pulled them back from the brink. North Korea issued a vague expression of regret over the soldiers’ injuries at the time but has never clearly accepted responsibility.
