The U.S. decision to allow Ukraine to fire American weapons deeper into Russia has not increased the risk of a nuclear attack, which is unlikely, despite Russian President Vladimir Putin's increasingly bellicose statements,

Russian President Vladimir Putin said his forces may use a new missile again after targeting Ukraine in retaliation for Kyiv’s use of American and British-made weapons on Russian territory this week.

A new ballistic missile fired by Russia at the Ukrainian city of Dnipro last week carried multiple warheads but no explosives, and caused limited damage, two senior Ukrainian government sources said.
