South Korean President Yoon Suk Yeol is due to attend 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 Korea's impeached president, Yoon Suk Yeol, was formally arrested early Sunday, days after being apprehended at his presidential compound in Seoul, as he faces possible imprisonment over his ill-fated declaration of martial law last month.

As South Korean authorities extended President Yoon Suk Yeol's detention, his supporters stormed the courthouse that issued the warrant, smashing windows with police shields.
