Russia is firing unarmed cruise missiles that were designed to carry nuclear warheads at targets in Ukraine to try to deplete Kyiv's stocks of air defenses, a senior U.S. military official said on Tuesday.
The official, who declined to be named, was asked about a Nov. 26 assessment by Britain's military intelligence which said that Russia was "likely" removing nuclear warheads from cruise missiles and firing the unarmed munitions into Ukraine.
