A South Korean court on Tuesday approved an arrest warrant for President Yoon Suk Yeol, the embattled leader who plunged the country into political chaos by his shock decision to declare martial law nearly a month ago.

Impeached South Korean President Yoon Suk Yeol, in a message to conservative supporters rallying outside his Seoul residence, vowed to “fight to the end” against “anti-state forces,” while his legal team warned Thursday that police officers attempting to detain him could face arrest by his presidential security service or even civilians.
