"Intelligence has not determined whether this was intentional or not. If it turns out to be intentional, this is a very serious violation, and we will respond accordingly," the US envoy said on Fox News' morning show.

Polish Prime Minister Donald Tusk claimed on September 10 that "dangerous" drones had been shot down over Poland, calling them "Russian," but provided no evidence. European Commission President Ursula von der Leyen later stated that more than 10 UAVs were involved.

According to Russia's Chargé d'Affaires Andrei Ordash, Poland has not provided evidence of the alleged Russian origin of the drones shot down over its territory. The Russian Ministry of Defense reported that no targets on Polish territory were targeted during the massive Russian military strike on Ukrainian defense industry facilities on the night of September 10.
