South Korean opposition parties introduced a bill Thursday calling for an independent investigation into impeached President Yoon Suk Yeol’s brief martial law declaration, as thousands of his supporters and critics held tense rallies near his residence ahead of his potential detention.

Venezuelan opposition parties and their supporters were holding protests around the country on Thursday in an eleventh-hour effort to put pressure on President Nicolas Maduro, one day before he is due to be sworn in for his third six-year term.

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.
