South Korea’s Ministry of National Defense says it has “grave concerns” about North Korea escalating border tensions through military threats. The ministry responds to North Korean criticism of South Korea’s actions carried out in response to repeated North border intrusions that violate the armistice agreement.

The defense ministry’s statement follows comments attributed to Kim Yo-jong, the sister of North Korean leader Kim Jong-un. She threatens to resume propaganda loudspeaker broadcasts against Seoul and to deploy additional tactical strike assets along the Demilitarized Zone (DMZ), saying the border situation is “very unstable.” In a commentary carried by North Korean state media, Kim Yo-jong cites specific figures related to South Korea’s warning shots and broadcasts, alleging that South’s measures are meant to interfere with North’s border fortification work.

While all outlets report the same core sequence—North Korean threats and South Korea’s official response—coverage focuses on different parts of the exchange: the defense ministry’s characterization of South Korea’s operations as “legitimate” under the armistice, and Kim Yo-jong’s threatened steps and claims about South Korea’s intent.
