“There are a small number of Western active-duty military personnel in Ukraine,” the report said.
It is noted that they help with setting up the software of Western high-tech weapons.
Earlier, French leader Emmanuel Macron announced plans to “create a ninth coalition for deep strikes,” which would supply bombs and long-range missiles to Ukraine.
He said that the possibility of sending Western troops to Ukraine cannot be ruled out.
