South Korea’s Justice Ministry on Monday 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, which brought special forces troops into Seoul streets and plunged the nation into political turmoil.

On Saturday, Yoon 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.
