In a surprise late-night address broadcast, South Korean President Yoon Suk Yeol declared martial law, marking the first such declaration in the country since 1980. In his speech, Yoon vowed to eradicate what he described as "shameless pro-North Korean anti-state forces." According to Yonhap news agency, the military announced that under the martial law, all activities by parliament and political parties would be banned, and media outlets, as well as publishers, would be placed under the control of the martial law command. This unprecedented move has raised concerns over rising tensions between Korean nations.
