South Korean President Yoon Suk Yeol on Tuesday declared martial law in a surprise late-night TV address, slamming domestic political opponents and sending shockwaves through the country.
Yoon said opposition parties had taken the parliamentary process hostage. He vowed to eradicate "shameless pro-North Korean anti-state forces" and said he had no choice but to take the measure to safeguard constitutional order.
Yonhap news agency cited the military as saying activities by parliament and political parties would be banned, and that media and publishers would be under the control of the martial law command.
Yoon did not cite any specific threat from the nuclear-armed North, instead focusing on his domestic political opponents. It is the first time since 1980 that martial law has been declared in South Korea.
