SEOUL, South Korea — 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.

South Korean prosecutors charged President Yoon Suk Yeol for his failed attempt last month to place the country under martial law, forcing the impeached leader to remain in detention as they build a case against him.
