ICAO Council condemns radio frequency interference affecting civil aviation safety, urges DPRK to stop disruptive activities
Montréal, 2 May 2025 – Through its decision published on 17 April 2025, the Council of the International Civil Aviation Organization (ICAO) noted with grave concern the continuing incidents of GNSS (Global Navigation Satellite System) radio frequency interference in the Incheon Flight Information Region (FIR), which have been ongoing since 2 October 2024.
The Council noted that these interference incidents, originating from the Democratic People's Republic of Korea (DPRK), continue despite previous Council decisions. These incidents jeopardise the safety of international air navigation and contradict principles enshrined in the Convention on International Civil Aviation (Chicago Convention) and its Annexes.
The Council strongly urged the DPRK to fully implement those previous decisions and to comply strictly with its obligations under the Chicago Convention. The Council has also reiterated its call to the DPRK to ensure that similar occurrences do not recur in the future.
Given the serious and continuous risk to international civil aviation, the Council will shortly consider reporting this matter to the 42nd Session of the ICAO Assembly to be held in September 2025, in accordance with Article 54(k) of the Chicago Convention.
The Council will continue to maintain close oversight of developments regarding this situation.
