As South Korean authorities extended President Yoon Suk Yeol's detention, his supporters stormed the courthouse that issued the warrant, smashing windows with police shields.

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, who was impeached and suspended from office in December, is the first sitting South Korean president to be arrested.
