The United States Mission to NATO posted new images from satellites on its Twitter page which showed that a great number of Russian troops had still been deployed in proximity to the border with Ukraine
"The new photos show no indication of Russian troops pulling back from the Ukrainian border. May 7, military forces are within 75 km of Ukrainian border," the United States Mission to NATO stated.
These are three comparative photos dated Oct. 25, 2013, March 23, 2014, and May 7, 2014.
