South Korea's jailed former president Yoon Suk Yeol arrived at the Seoul Central District Court on Friday for a new criminal trial on additional charges related to his December martial law decree, alongside his ongoing rebellion trial.

Yoon has been facing charges including obstruction of special official duties and abuse of power.

Escorted by security officers, Yoon entered the courtroom with short hair, looking gaunt.

He could also attend a hearing at the same court over his bail request later on Friday.
