South Korea's opposition-controlled National Assembly voted to impeach acting President Han Duck-soo, further deepening the country's political crisis.

Han has been the caretaker leader after President Yoon Suk Yeol was impeached by the assembly over his short-lived imposition of martial law earlier this month.

South Korea's National Assembly impeached the country's acting president, Han Duck-soo, on Friday, marking the second time in December that it has chosen to remove the country's leader.
