South Korea’s president has accepted the resignation offer by his defense minister, as opposition parties moved to impeach both men over the stunning yet short-lived imposition of martial law that brought armed troops into Seoul streets.

South Korea is in turmoil after president Yoon Suk Yeol declared martial law on Tuesday night, only to revoke it hours later under immense pressure. The decree, which marked the first attempt to impose such measures in over four decades, has sparked calls for his resignation and left the nation’s political landscape in disarray.
