South Korea president Yoon Suk Yeol defended his martial law decree as an act of governance and denied rebellion charges Thursday, rejecting the opposition-led impeachment attempts against him and investigations into last week's move, reported news agency Associated Press.

Yoon Suk Yeol's televised statement came hours before the main liberal opposition Democratic Party submitted a new impeachment motion against Yoon. The opposition party plans to put the motion on a floor vote this Saturday.
