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.

The assembly impeached President Yoon Suk Yeol last month, but the Constitutional Court will decide whether to formally dismiss or reinstate him.

South Korea's impeached President Yoon Suk Yeol attended a court hearing on Saturday to fight a request by investigators to extend his detention on accusations of insurrection.

A South Korean court on Sunday extended President Yoon Suk Yeol’s detention for up to 20 days, citing concern he could destroy evidence in a criminal probe into his short-lived declaration of martial law in early December.

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.

Hours after South Korea’s impeached President Yoon Suk Yeol was formally arrested, triggering rioting by his supporters, his lawyers said Sunday that he remains defiant in his refusal to answer questions over the probe into his declaration of martial law last month.

Yoon was brought into custody about three hours after hundreds of law enforcement officers entered the residential compound in their second attempt to detain him.
