South Korean President Yoon Suk Yeol was impeached over his attempted martial law declaration on December 3. He faces criminal investigation for possible rebellion charges as prosecutors summon him for questioning. Yoon's impeachment was backed by a 204-85 vote in the National Assembly and he has been suspended from presidential duties. If removed, a national election will follow within 60 days. Concerns over political instability amplify threats from North Korea as the Constitutional Court reviews the case.
