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.

South Korean President Yoon Suk Yeol appeared in a Seoul court for his impeachment trial Tuesday, defending his short-lived martial law bid and denying charges that he ordered the military to drag lawmakers away.
