South Korea’s opposition-controlled National Assembly voted Friday to impeach acting President Han Duck-soo despite vehement protests by governing party lawmakers, further deepening the country’s political crisis set off by President Yoon Suk Yeol’s stunning imposition of martial law and ensuing impeachment.

The vote was the second major impeachment in two weeks after President Yoon’s ill-fated martial law bid set off turmoil. The country’s currency has plunged.
