South Korean investigators have sought an arrest warrant for suspended President Yoon Suk Yeol over this month's short-lived imposition of martial law, an official said on Monday, the first time an incumbent president has faced such action.

A warrant has been issued to detain South Korea’s impeached president Yoon Suk Yeol for questioning over his shortlived attempt to impose martial law earlier this month. The country’s anti-corruption agency said on Tuesday that a Seoul court granted the arrest warrant sought by prosecutors investigating Mr Yoon over the martial law declaration.
