According to open-source intelligence, unofficial Russian reports, and videos emerging online, the first US-supplied ATACMS missiles have struck the Russian Khalino airfield inside internationally recognized Russia. This follows an apparent Russian escalation by firing IRBM missiles (apparently without warheads) into Ukraine for the first time – IRBMs and ICBMs are exclusively used to deliver nuclear missiles. It seems Ukraine and its Western allies have called Russia’s nuclear bluff once again.
