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 declared on Dec.

Yoon Suk-yeol retains the title but not the power of president while the constitutional court decides whether to approve the motion to impeach him.
