South Korean President Yoon Suk Yeol attended on Tuesday a Constitutional Court hearing of his impeachment trial where the detained leader may get a chance to argue his case or answer questions over his short-lived bid to impose martial law.

The president and his legal team denied allegations that he had sought to target lawmakers during his brief declaration of martial law in December.

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