Bulgarian officials have denied claims of Russian interference in the GPS disruption of a plane carrying European Commission President Ursula von der Leyen. Prime Minister Rosen Zhelyazkov stated there was no prolonged jamming, and Deputy Prime Minister Grozdan Karadjov contradicted earlier assertions of interference. An investigation will not be conducted, and reports of significant delays have been disputed by flight tracking data. Analysts remain divided on the possibility of jamming, while the EU acknowledges ongoing GPS jamming threats from Russia. Teljes cikk (Euronews.com)
