Nato's top military commander in Europe has released a series of satellite images taken by the commercial satellite company Digital Globe, reports 4 News.
The images, which were taken on March 22, show the military buildup that Russia has been massing on Ukraine's border.
AndersFogh Rasmussn, the Secretary General of Nato, believes that the military buildup is not simply a training exercise, as Russia has previously declared.
40,000 Russian troops along #Ukraine's borders, not training, ready for combat. #Russia is stirring tensions & provoking unrest in E Ukraine

U.S. intelligence officers also believe that the chances of a Russian invasion of Ukraine are increasing as Russia has started building supply lines and battlefield hospitals, elements not needed for training, close to the border.
Below are satellite images of the Russian forces.
