Seoul, South Korea – Former South Korean President Yoon Suk Yeol has been sentenced to 30 years in prison for orchestrating the deployment of military drones into North Korea. Prosecutors argued the operation was intended to create a justification for his ultimately failed martial law declaration in 2024. The drone flights, which North Korea claimed involved propaganda leaflet drops, significantly heightened military tensions between the two Koreas in October 2024.

The sentencing by the Seoul Central District Court adds to a series of legal judgments against the former leader. Special prosecutors had requested the 30-year term, stating that Yoon's alleged attempt to "fabricate wartime conditions" with the drones jeopardized national security. A court spokesperson confirmed the sentence to AFP news agency on Friday, though further details were not immediately available.

Yoon, who has denied any wrongdoing, is already serving a life sentence following a February 2026 conviction for leading an insurrection connected to his attempted martial law order. That order plunged South Korea into severe political turmoil, leading to his impeachment and removal from office. A subsequent snap election resulted in the victory of current liberal President Lee Jae Myung.

Defense lawyers for Yoon have maintained that he neither ordered nor approved the drone operation. They contend the flights were a response to North Korean balloons carrying rubbish, launched across the border over several months, and were unrelated to the martial law attempt. Yoon is currently in custody and has the right to appeal Friday's ruling.

The drone flights themselves underscore the persistent volatility in relations between North and South Korea, nations technically still at war. Earlier this year, President Lee expressed regret after an investigation revealed government officials had sent drones into North Korea in January.

North Korean leader Kim Jong Un's sister had previously described Lee's statement as "wise behavior." However, any hopes for improved relations were diminished when North Korea reverted to labeling South Korea its "most hostile" enemy, reflecting its continued diplomatic isolation.

This latest conviction against Yoon, a former top prosecutor, further details the downfall of a leader whose presidency was marked by significant political upheaval. The martial law declaration, in particular, is seen as a critical point of contention leading to his impeachment and subsequent legal battles.

The ongoing legal proceedings and the gravity of the charges highlight the deep-seated mistrust and the potential for escalation that characterizes inter-Korean relations. The drone operation, viewed by prosecutors as a deliberate provocation, serves as a stark reminder of the fragile security landscape on the Korean Peninsula.
