South Korea’s Justice Ministry has imposed an overseas travel ban on President Yoon Suk Yeol as authorities investigate allegations of rebellion and other charges in connection with his short-lived declaration of martial law last week. Yoon’s martial law decree, which brought special forces troops into Seoul streets, plunged South Korea into political turmoil. On Saturday, he avoided an opposition-led bid to impeach him, with most governing party lawmakers boycotting a parliamentary vote. But the opposition parties vowed to submit a new impeachment motion against him this week. A Justice Ministry official said Monday that it has banned Yoon from leaving the country following requests by police, prosecutors and an anti-corruption agency.
