The head of NATO’s military committee says that Ukraine has the solid legal and military right to strike deep inside Russia to gain combat advantage, reflecting the beliefs of a number of U.S. allies.

The outgoing head of NATO Jens Stoltenberg said on Monday he welcomed talks on Ukraine's use of long-range missiles to strike inside Russian territory, but any decision on the issue would have to be made by individual allies.

Ukraine would have a good military reason to strike deeper into Russia using Western weapons, a senior NATO military official said on Saturday.

Russia's U.N. Ambassador Vassily Nebenzia warned the UN Security Council that NATO could be seen as engaging in direct war with Russia if Western nations allow Ukraine to launch long-range strikes within Russia.

Armenia's prime minister said the CSTO, seen as Putin's NATO, "creates threats" for his country's future existence, after it pulled away from it.

Dmitry Peskov, the spokesperson for Kremlin leader Vladimir Putin, has stated that NATO's refusal to take Vladimir Putin's statements seriously regarding the supposed consequences of allowing Ukraine to attack Russian territory with long-range Western weapons is "provocative and dangerous".
