"While we're assessing the full facts, it's obvious that such (an) attack would mark yet another clear escalation from the side of (Russian President Vladimir) Putin," Stano said, according to AFP.The Ukrainian Air Force said that Russia launched nine missiles, including a conventional ICBM, against the central-eastern city of Dnipro on the morning of Nov. 21, injuring at least two people and damaging several buildings.President Volodymyr Zelensky later clarified that the investigation is ongoing but that the missile's "speed and altitude suggest intercontinental ballistic capabilities."If confirmed, it would mark the first occasion of Russia deploying an ICBM in the war against Ukraine, coming shortly after the U.S. permitted Ukraine to carry out strikes in Russia with Western long-range missiles and after Russia updated its nuclear deterrence policy.While an undisclosed Ukrainian official told ABC News that Ukraine was "95%" certain Russia deployed an ICBM, a Western official quoted by the news outlet disputed the claim, saying it resembled a regular ballistic missile.It remains unclear what type of ICBM was reportedly deployed.
