South Korea's suspended president, Yoon Suk Yeol, has for the third time in a row failed to heed a summons to appear before the country's law enforcement authorities, the Yonhap news agency reported on Sunday.

South Korea's acting president faces an impeachment vote on Friday, intensifying a political crisis as the Constitutional Court meets for its first hearing on suspended President Yoon Suk Yeol's short-lived martial law declared on Dec.

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.
