MOSCOW: The Kremlin said on Friday that Estonia's stated readiness to host NATO allies' U.S.-made F-35A stealth jets, capable of carrying nuclear weapons, posed a direct threat to Moscow.

Estonian Defence Minister Hanno Pevkur told the Postimees news outlet on Thursday that Estonia - which borders Russia and is a rotating base for NATO jets tasked with protecting Baltic airspace - was ready to host nuclear-capable jets if necessary.

"If some of them, regardless of their country of origin, have a dual-use capability to carry nuclear weapons it doesn't affect our position on hosting F-35s in any way," the outlet cited him as saying.

"Of course we are ready to host our allies."

Pevkur was speaking after Britain, a NATO member, announced it would buy at least 12 F-35A jets capable of carrying nuclear warheads and that they would join NATO's airborne nuclear mission.
