North Korea’s military recently alleged that South Korea had sent drones across the inter-Korean border, issuing a stern warning on Saturday that South Korea’s “unforgivable hysteria” would lead to repercussions.

South Korea swiftly refuted these claims.

This accusation could potentially hinder South Korea’s liberal administration’s attempts to mend relations with North Korea.

On Sunday, North Korean forces reportedly deployed specialized electronic warfare equipment to intercept a South Korean drone near the border town.

According to a statement from the General Staff of the North Korean People’s Army, relayed by state media, the drone was fitted with two cameras that recorded undisclosed locations.

South Korea infiltrated another drone into North Korean airspace on Sept. 27 before it was forced to crash following electronic strikes by North Korea, the statement said, adding that authorities found the drone also contained video data on major objects in North Korea.

“We strongly denounce the hooligans’ serial outrageous encroachment upon our sovereignty and undisguised provocative acts against us,” the North Korean statement said. “The ROK military warmongers will be surely forced to pay a dear price for their unpardonable hysteria.”

The ROK is the abbreviation of the Republic of Korea, South Korea’s official name.

South Korea’s Defense Ministry said it did not operate drones on the dates cited by North Korea and President Lee Jae Myung ordered a through investigation of the North Korean claim.

Since taking office in June, Lee’s government has pushed hard to reopen talks with North Korea and reconcile the rivals. But North Korea has steadfastly rebuffed Lee’s overture.

Lee said Wednesday he asked Chinese President Xi Jinping to serve as a mediator to ease animosities between the two Koreas during their recent summit and Xi called for patience.

North Korea has shunned talks with South Korea and the United States since leader Kim Jong Un’s high-stakes nuclear diplomacy with US President Donald Trump fell apart in 2019 due to wrangling over international sanctions.

North Korea has since focused on building more powerful nuclear weapons and declared a hostile “two-state” system on the Korean Peninsula to terminate relations with South Korea.

Drone flights are a source of animosity between the two Koreas, with the rivals accusing each other of flying drones into their respective territories in recent years.

North Korea accused South Korea in October 2024 of flying drones over its capital, Pyongyang, to drop propaganda leaflets three times.

South Korea’s military said it couldn’t confirm whether the North’s claim was true.

Tension rose sharply at the time as North Korea threatened to respond with force, but neither side took any major action and tensions gradually subsided.

South Korea has also accused North Korea of occasionally flying drones over South Korea.

In December 2022, South Korea announced it fired warning shots, scrambled fighter jets and flew surveillance drones over North Korea in response to what it called North Korea’s first drone flights across the border in five years.
