Russia, Ukraine, Belarus, U.S. Carry Out Military Exercises In Europe

As tensions simmer between Moscow and the West over Ukraine, Russia and Belarus have been mobilizing personnel and military equipment.

The Ukranian military on Friday showed U.S. soldiers training Ukranians on how to use a weapon designed to destroy hardened bunkers. 

The images came the same day that the U.S. Army released images showing the first U.S. service members boarding planes for Europe where they'll help bolster NATO forces. 

And NATO provided video of its exercises at sea. F-18 fighter jets from the USS Truman aircraft carrier flew over the Baltic states and Poland and Romania.
