Behind rows of barbed wire and a small army of personal security, impeached South Korean President Yoon Suk Yeol remained holed up in his sprawling hillside villa with his wife, dogs and cats on Tuesday as investigators planned his arrest.

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.

Protesters have thronged the official residence of impeached President Yoon Suk Yeol, where officials trying to arrest him were blocked by security guards.
