Vladimir Putin justified the strikes as a response to the Ukrainian use of US weapons against Russian territory and threatened Kyiv with the experimental hypersonic missile used on November 21

Washington's decision to allow Kyiv to use U.S.-made weapons to strike deep into Russia has not increased the risk of a nuclear attack, Reuters reported on Nov. 27, citing five unnamed sources familiar with the intelligence data.
