South Korean authorities have granted a request to extend a warrant to detain the country’s suspended President Yoon Suk Yeol for questioning over his surprise declaration of martial law last month.

Hundreds of South Koreans rallied overnight into Sunday near the residence of impeached President Yoon Suk Yeol, calling for his ouster and arrest.

Yoon's lawyers filed an injunction request to a Seoul court to nullify the arrest warrant, but the court struck that down on Sunday, a court official said on Tuesday.
