South Korean anti-graft investigators secured a new court-ordered arrest warrant Tuesday for impeached President Yoon Suk Yeol, whose failed martial law bid threw the country into turmoil. The former star prosecutor has refused questioning three times after his bungled December 3 martial law decree plunged South Korea into its worst political crisis in decades.

A standoff between rival government forces outside the presidential compound in South Korea is a startling development, even for observers used to the country's famously rough and tumble politics.

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.

South Korea's main opposition party introduced a bill to impeach acting President Han Duck-soo on Thursday, a day before it plans to seek a vote on the move, which could deepen a constitutional crisis triggered by a short-lived martial law.

Blocked by bodyguards, officials retreated after several hours without serving a court warrant to hold President Yoon Suk Yeol for questioning on insurrection charges.
