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

The agency trying to get Yoon out of his house, the Corruption Investigation Office for High-Ranking Officials, will likely seek a new court warrant to extend the window for Yoon’s detention. Police say they are reviewing the agency’s request. It wasn’t immediately clear whether the anti-corruption agency would make another attempt to detain Yoon on Monday before the deadline expires at midnight.
