The chief of security for South Korean President Yoon Suk Yeol said on Sunday he could not cooperate with efforts to arrest the impeached leader, in remarks that could push the political crisis towards another high-stakes confrontation.

Thousands of South Korean citizens were gathering on Sunday near impeached President Yoon Suk Yeol’s residence a day before an arrest warrant for him expires.

Hundreds of South Koreans, bundled up against freezing temperatures and snow, rallied overnight into Sunday near the residence of impeached President Yoon Suk Yeol as authorities prepared to renew their efforts to detain him over his short-lived martial law decree.
