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.

Yoon Suk Yeol’s presence at the court was his first public appearance since becoming South Korea’s first sitting president to be detained over his short-lived declaration of martial law, which plunged the country into political turmoil.

South Korea’s impeached president, Yoon Suk Yeol, has been formally arrested, days after being apprehended at his presidential compound in Seoul.
