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, has been formally arrested, days after being apprehended at his presidential compound in Seoul.
