Ukraine’s Armed Forces say Russia is transferring weapons and other military equipment to Belarus.
It says the deployments are part of renewed Russian plans to mount an offensive aimed at encircling the capital of Kyiv.
Russian forces are also building-up equipment supplies in Crimea, the Ukrainian army added in a statement Thursday afternoon.
In an upbeat assessment of Ukraine's success in withstanding Russia's invading forces thus far, the statement went on:
"The Russian military leadership is beginning to realize that the available forces and means are not enough to maintain the temporarily occupied territories of Ukraine and conduct defense operations."
