South Korean President Yoon Suk Yeol was detained on Wednesday after a massive law enforcement operation at the presidential compound that ended a weeks-long stand-off between his bodyguards and the country's anti-corruption agency.

SEOUL - South Korea's anti-corruption agency will resume questioning President Yoon Suk Yeol on Jan 16 as part of a criminal probe into whether he committed insurrection, while the Constitutional Court holds a second hearing of the embattled leader's impeachment trial.

South Korean authorities arrested Yoon Suk Yeol over insurrection allegations, with the embattled leader saying he agreed to comply with investigations to avoid "bloodshed", ending weeks of tense political standoff.
