Police have begun questioning former Prime Minister Han Duck-soo and former Interior Minister Lee Sang-min as suspects who could potentially face insurrection charges in connection with the December 3 martial law incident.

An official revealed at a press briefing that the interrogation for Han and Lee started at 10 a.m. Monday.

Investigators said there are discrepancies between their testimonies about a Cabinet meeting held just before former President Yoon Suk Yeol declared martial law and CCTV footage recently obtained from the Presidential Security Service, which shows the hallway outside the meeting room.

Their accounts also reportedly conflict with previous testimony given to the National Assembly, the Constitutional Court and other investigative bodies.

Lee is additionally being investigated over allegations that he ordered the National Fire Agency to cut power and water to media outlets during the martial law period.

Police previously summoned both Han and Lee for questioning as suspects in the same case.
