Suspended president Yoon Suk-yeol authorised the military to fire their weapons if needed to enter parliament, according to prosecutors.

South Korea's acting president faces an impeachment vote on Friday, intensifying a political crisis as the Constitutional Court meets for its first hearing on suspended President Yoon Suk Yeol's short-lived martial law.

According to the prosecution indictment report, now suspended president Yoon Suk Yeol told the chief of the capital defence command that military forces could shoot if necessary to enter the National Assembly.
