Yonhap news agency says South Korean prosecutors have indicted the impeached President Yoon Suk Yeol over his imposition of martial law.

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

SEOUL (Reuters) - South Korea's prosecutors indicted suspended President Yoon Suk Yeol on Sunday on charges of leading an insurrection with his short-lived imposition of martial law on Dec. 3, the Yonhap news agency reported. The decision came after anti-corruption investigators last week recommended Yoon be formally charged.
