SEOUL, South Korea (AP) — South Korean prosecutors on Sunday indicted impeached President Yoon Suk Yeol on rebellion in connection with his short-lived imposition of martial law, a criminal charge that could incur the death penalty or life imprisonment if convicted.

This is the latest blow to Yoon, who was impeached and arrested over his Dec. 3 martial law decree that plunged the country into political turmoil, shook its financial markets, and hurt its international image. Separate from criminal judicial proceedings, the Constitutional Court is now deliberating whether to formally dismiss Yoon as president or reinstate him.
