Hungarian Prime Minister Viktor Orban said Friday his country was buying four new Saab JAS Gripen fighter jets from Sweden, Paralel.Az reports citing Deutsche Welle.

The deal, which expands Hungary's fleet of 14 Gripen jets, comes after Hungary U-turned on its threat to bloc Sweden's accession to the NATO military alliance.

"Today, we have reached an agreement to add four aircraft to the Hungarian Defence Forces' Gripen fleet," Orban said at a joint news conference with Swedish Prime Minister Ulf Kristersson in Budapest.

He added that the deal would boost Hungary's air defense capability and its commitment to the NATO military alliance.

As well as the jet deal, Hungary has agreed to expand a related logistics contract, Orban said.
