In an act some described as an indirect declaration of war, North Korea blew up the liaison office with the South in Kaesong earlier today.

This comes days after North Korea's denouncement of the United States and the decisions made during the SG Summit, and signals a rapid change in tone for the North.

President Moon Jae-in convened an emergency meeting of top security officials Tuesday, hours after North Korea demolished the inter-Korean liaison office in its border town of Kaesong.

The joint liaison office meant for talks and discussions. 

The National Security Council meeting was set to open at 5 p.m.

According to the defense and unification ministries, North Korea blew up the inter-Korean liaison office in its border town of Kaesong at 2:49 p.m.

The explosion took place three days after Kim Yo-jong, the powerful sister of North Korean leader Kim Jong-un, warned that the North will demolish the "useless" communication office in protest of Seoul's "failure" to stop activists from sending anti-North Korean leaflets to the country. (Yonhap)
