CIA operatives and a US commando network are co-ordinating the flow of weapons inside Ukraine as part of a secret operation, according to an explosive new report. 

The New York Times has blown the lid on covert US activities in Ukraine, where it says that spies and commandos are providing arms, intelligence and training. 

While much of the work is taking place at bases in Britain, Germany and France, the report says that the CIA was operating secretly in Ukraine, mostly in the capital Kiev.
