North Korea threatened on Thursday to end an inter-Korean military agreement reached in 2018 to reduce tensions if the South fails to prevent activists from flying anti-Pyongyang leaflets over the border.
Kim Yo Jong, the powerful sister of North Korea's leader, also said the North could permanently shut a liaison office with the South and an inter-Korean factory park in the border town of Kaesong, which have been major symbols of reconciliation between the Koreas.
