The ruling People Power Party (PPP) on Saturday denounced the opposition-led impeachment of acting President Han Duck-soo as an attempt to bring down the government, saying that his impeachment should be nullified.

President Yoon Suk Yeol had earlier apologized for a short-lived declaration of martial law that plunged the East Asian democracy into chaos, igniting public anger.

President Yoon Suk Yeol Yoon imposed martial law in the middle of the night earlier this month, plunging South Korea into its worst political crisis in decades.

South Korea's suspended president Yoon Suk Yeol authorised the military to fire their weapons if needed to enter parliament during his failed bid to impose martial law, according to a prosecutors' report seen by AFP on Saturday.
