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.

South Korean President Yoon Suk Yeol is expected to make his first appearance at his impeachment trial on Tuesday, with security ramped up following the Capitol Hill-like rioting during his appearance at another court at the weekend.

South Korea's suspended President Yoon Suk Yeol, who was impeached in December following his short-lived attempt to impose martial law, appeared at his impeachment hearing for the first time on Tuesday.
