U.S. National Security Council communications spokesman John Kirby warned Russia at a press conference Thursday that the United States will respond to possible attacks on its satellites following threats by a Russian official.

“I will simply say that any attack on U.S. infrastructure will be met with a response and will be appropriate to the threat it poses to our infrastructure,” he explained at a press conference, advanced by DPA.

These words come after the deputy head of the Russian Foreign Ministry’s Department for Non-Proliferation and Arms Control, Konstantin Vorontsov, assured a meeting of a United Nations General Assembly committee that U.S. commercial satellites “could become legitimate targets for attack” if they are deployed as part of the conflict in Ukraine.
