South Korea’s impeached President Yoon Suk Yeol was formally arrested early Sunday, days after being apprehended at his presidential compound in Seoul. He faces possible imprisonment over his ill-fated declaration of martial law last month.

South Korea's impeached President Yoon Suk Yeol attended a court hearing on Saturday to fight a request by investigators to extend his detention on accusations of insurrection.

A Seoul court issued a warrant Saturday to detain impeached President Yoon Suk Yeol for an extended period over his botched martial law bid last month in the first such detention of a sitting South Korean president.
