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.

Suspended President Yoon Suk Yeol will attend the fourth hearing of his impeachment trial on Thursday, his lawyers said, as former Defense Minister Kim Yong-hyun is slated to appear and testify as well.

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