The government has called on North Korea to stop sending jamming signals to the South that have been continuously detected from Thursday evening, calling it a provocation.

Ministry of Unification Spokesman Jeong Joon-hee said in a regular briefing Friday that North Korea should suspend the provocative act immediately, urging Pyongyang to behave in a way that helps both the development of inter-Korean relations and the regime itself.

Asked whether the North’s disruption of the Global Positioning System(GPS) signals was engineered by the North’s elite cyberattack bureau Unit 121, Jeong declined to comment, saying it is a matter of military intelligence and not appropriate to talk about it in public.

Defense Ministry Spokesman Moon Sang-gyun said during a media briefing Friday that the North appears to have intended to heighten inter-Korean tensions with the satellite signal disruptions and is expected to continue the acts for some time.
