A South Korean court on Sunday extended President Yoon Suk Yeol’s detention for up to 20 days, citing concern he could destroy evidence in a criminal probe into his short-lived declaration of martial law in early December.

A South Korean court extended President Yoon Suk Yeol’s detention for 20 days, igniting violent protests from his supporters. Yoon, arrested for insurrection after a failed martial law declaration, faces a tumultuous political landscape as his party’s support rebounds amid ongoing turmoil.

South Korean President Yoon Suk Yeol has been detained 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.
