Former South Korean President Sentenced for Drone Operation

Former President Yoon Suk Yeol of South Korea was convicted on June 11, 2026, for ordering military drones to fly over North Korea. This act aimed to escalate tensions on the Korean Peninsula, providing a pretext for declaring martial law.

Yoon, aged 65, has faced various criminal charges across eight trials since his impeachment and removal from office last year. These charges stem from his illegal imposition of martial law in late 2024. Previously, a court convicted him of masterminding an insurrection, resulting in a life imprisonment sentence in February.

For orchestrating the drone operation, Yoon received a 30-year prison sentence. This charge is the most serious after his insurrection conviction and involves undermining South Korea’s military interests or aiding an enemy state. This conviction is unique in South Korean history as Yoon is the first former president convicted of such a crime.

The court, consisting of a three-judge panel at the Seoul Central District Court, found that Yoon and his associates sent drones across the inter-Korean border—the most fortified frontier in the world—at the end of 2024. Their goal was to increase military tensions with North Korea, which Yoon planned to leverage to declare martial law.

The special prosecutor in the case described the drone operation as “an anti-state and anti-national crime” and sought a 30-year sentence for Yoon. Additionally, two of Yoon’s collaborators in the drone operation were convicted and sentenced. Kim Yong-hyun, his former defense minister, received a 30-year sentence, while Lt. Gen. Yeo In-hyong, his former counterintelligence commander, received a 15-year sentence. Both officials had previously served lengthy prison terms for their roles in the martial law declaration.
