SEOUL, South Korea — Hundreds of law enforcement officials in South Korea entered the residential compound of impeached President Yoon Suk Yeol early Wednesday in the capital Seoul. It was their second attempt to detain him over his imposition of martial law last month.

More than a thousand anti-corruption investigators and police officers could be deployed in a potentially multiday operation to apprehend Yoon, who has been holed up in the Hannam-dong residence for weeks. Yoon has justified his martial law decree as a legitimate act of governance against an 'anti-state' opposition bogging down his agenda with its legislative majority and vowed to 'fight to the end' against efforts to oust him.
