South Korean President Yoon Suk Yeol attended on Tuesday a Constitutional Court hearing of his impeachment trial where he denied ordering military commanders to drag lawmakers out of parliament during his short-lived bid to impose martial law.

He has been incarcerated for the past week, while investigators probe his botched attempt to impose martial law in early December.

South Korea looks set for a dramatic political showdown this week as impeachment proceedings kick off against suspended President Yoon Suk Yeol, who remains holed up in his fortified residence evading arrest for a separate criminal investigation.
