The impeachment of South Korea’s acting President Han Duck-soo has plunged the country into further political turmoil, coming less than two weeks after lawmakers impeached President Yoon Suk Yeol.

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.

Investigators seeking to detain Yoon Suk Yeol in relation to his attempt to institute martial law scuffled with security service officers blocking entry to his residence.
