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.

The impeached former president has refused questioning three times since his bungled December 3 martial law decree.

A South Korean court has re-issued a warrant to arrest impeached President Yoon Suk Yeol, the country's corruption investigation agency said on Tuesday.
