President Yoon Suk Yeol has been booked as a suspect on charges of treason, the prosecution said Sunday.

"Numerous complaints have been submitted, and an investigation is under way in accordance with the process," said Park Se-hyun, who leads a special investigation headquarters into Yoon's short-lived declaration of martial law last week.
