Senior aides to Yoon offered to resign en masse, as did the defence minister, who said he took “full responsibility for the confusion and concern” around the martial law declaration.
Yoon has yet to publicly reappear.
The repeal of martial law prompted jubilation among flag-waving protesters outside parliament.
As night fell in Seoul Wednesday, protesters again demanded Yoon step down.
“I was so incensed I couldn’t sleep a wink last night, I came out to make sure we push out Yoon once and for all,” 50-year-old Kim Min-ho told AFP.
