SOUTH KOREA’S Justice Ministry said today that an overseas travel ban has been imposed on President Yoon Suk Yeol during an investigation into his short-lived declaration of martial law.

This comes a day after trade unions threatened to escalate strike action to remove the president.

South Korean police, prosecutors and the anti-corruption agency called for the ban as they expanded their probes into possible rebellion charges over President Yoon’s imposition of martial law last week.
