S.Korea police try to raid President Yoon's office over martial law

South Korean police tried to search President Yoon Suk Yeol's office on Wednesday, but Yonhap news says they have not been able to enter the main building. It comes as one of closest confidants tried to take his own life, officials said, amid a widening investigation into the U.S. ally's decision to declare martial law last week. Lauren Anthony reports.
