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.

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.

Tensions ran high near the residence of impeached South Korean President Yoon Suk Yeol Thursday, as rival protesters clashed and hundreds of supporters formed a blockade to prevent his imminent arrest.
