South Korea’s President Yoon Suk Yeol is facing a possible overseas travel ban as authorities investigate his controversial imposition of martial law last week. The ban is part of an expanding probe into potential rebellion charges after Yoon deployed special forces troops in Seoul, plunging the nation into political turmoil.

South Korean police, prosecutors, and anti-corruption agencies, including the Corruption Investigation Office for High-Ranking Officials, have requested the travel ban. Yoon’s decree, which was in effect for only six hours, was seen as a significant move against parliament, leading to a fierce political battle. The opposition parties have labeled Yoon's actions as unconstitutional and a rebellion, and they have filed complaints against him and his former defense minister.

While sitting presidents in South Korea have immunity from prosecution, allegations of rebellion or treason can still lead to legal actions. Prosecutors have already detained former Defense Minister Kim Yong Hyun, who allegedly recommended martial law. This investigation has also led to the suspension of three senior military officers.

Although the martial law lasted for only a short time, it has sparked widespread political and legal consequences. Yoon’s actions have drawn criticism from both political opponents and parts of the public, with calls for impeachment. The governing party is trying to navigate the situation while maintaining Yoon’s position as president, as they fear losing the presidency in a potential by-election if he is removed from office.
