Russia warned the West and Ukraine on Friday of "disastrous consequences" if Kyiv moved against close Russian ally Belarus, making clear it would intervene to defend a country where it has deployed tactical nuclear weapons.

Despite limited resources, Ukraine is beginning to achieve measurable results in targeting Russian logistics. However, it cannot currently rely on the freedom to use Western weapons on Russian territory.

A senior Russian lawmaker on Thursday said that Ukrainian strikes on Russia with Western missiles would lead to global war with the use of nuclear weapons and that Moscow's response would be tough with more powerful weapons.
