• Full report: South Korea president Yoon Suk Yeol removed from office

Yoon violated his duty as South Korean commander-in-chief by mobilising troops, says Justice Moon, the constitutional court's acting president says. The president's martial law declarations violated parliament's rights, he says as the ruling continues.

Justice Moon says it is difficult to see the South Korean opposition's actions as a severe national crisis to justify Yoon Suk Yeol's martial law declaration, Reuters is reporting as he continues delivering the ruling.
