South Korea's parliament began a session on Friday where a vote to impeach acting President Han Duck-soo over short-lived martial law is scheduled, as the Constitutional Court said it would swiftly decide suspended President Yoon Suk Yeol's fate.

South Korea’s President Yoon Suk Yeol again declined to appear for questioning by investigators over his martial law declaration as the embattled leader seeks to first defend himself at an impeachment trial.

The impeachments of the country’s top two officials has worsened its political turmoil, deepened economic uncertainties, and hurt its international image.
