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.

South Korean President Yoon Suk-yeol went Saturday to testify before the court that must decide whether or not to extend the arrest of the deposed president, detained by the national anti-corruption bureau for his fleeting declaration of martial law.
