South Korea's President Yoon Suk Yeol faces a new and potentially more robust attempt to arrest him on insurrection charges after a top investigator vowed to do whatever it takes to break a security blockade and take in the impeached leader.

South Korean investigators trying to arrest suspended President Yoon Suk Yeol have less than 24 hours before their warrant expires Monday, with the embattled leader holed out in his residence surrounded by loyal security forces.

U.S. Secretary of State Antony Blinken traveled to South Korea on Monday as an affirmation of continued support for the East Asian country as it struggles to navigate a historic constitutional crisis.
