A special counsel team indicted former President Yoon Suk Yeol on Wednesday on charges of instructing officials to justify his failed martial law bid to the United States and other major partner nations.

Special counsel Kwon Chang-young's team said it charged Yoon with abuse of power in its first indictment against the jailed former president.

With the new indictment, Yoon is standing a total of eight trials in connection with his imposition of martial law in December 2024, his wife's alleged corruption and other offenses.

Prior to Wednesday, the number was down to seven after the Supreme Court last month finalized a seven-year prison term for his obstruction of investigators' attempt to detain him following his martial law bid.
