South Korean court orders formal arrest of impeached President Yoon Suk Yeol over his short-lived martial law decree.

SEOUL, South Korea (AP) — Hours after South Korea’s impeached President Yoon Suk Yeol was formally arrested, triggering rioting by his supporters, his lawyers said Sunday that he remains defiant in his refusal to answer questions over the probe into his declaration of martial law last month.

Yoon and his ruling party supporters remain defiant against the insurrection charges. He is South Korea's first sitting president to be detained.
