Marie Harf, Acting Spokesperson of U.S. Department of State said in the Official Statment that Combined Russian-separatist forces continue to violate the terms of the “Minsk 2” agreement signed in mid-February, maintain a sizable number of artillery pieces and multiple rocket launchers within prohibited areas.

Besides the Russian Federation has continued to ship heavy weapons, and deploys air defense systems into Eastern Ukraine:
“The Russian military has deployed additional air defense systems into eastern Ukraine and moved several of these nearer the front lines. This is the highest amount of Russian air defense equipment in eastern Ukraine since August.”
Russia-backed terrorists have command and control equipment and complex training from the Russian Federation:
“Russian and separatist forces also have a large concentration of command and control equipment in eastern Ukraine.
Combined Russian-separatist forces have been conducting increasingly complex training in eastern Ukraine. The increasingly complex nature of this training leaves no doubt that Russia is involved in the training. The training has also incorporated Russian UAVs, an unmistakable sign of Russia’s presence.”
In addition Russia is building up its forces along the border with Ukraine, and sending additional units there:
“Russia is also building up its forces along its border with Ukraine. After maintaining a relatively steady presence along the border, Russia is sending additional units there. These forces will give Russia its largest presence on the border since October 2014. Russia has also redeployed military elements near Belgorod, opposite Kharkiv,” says Marie Harf, Acting Spokesperson of U.S. Department of State.
