Yoon’s detention, after a tense standoff outside the presidential residence, marks the latest chapter in a bewildering series of events since his martial law decree.

Yoon was impeached for declaring martial law on Dec. 3 in what some authorities have alleged amounted to an attempted rebellion.

South Korea's Constitutional Court adjourned the opening session of the impeachment trial of suspended President Yoon Suk Yeol within minutes on Tuesday, after the embattled leader did not attend court.
