Concerns Grow In Ukraine Over Pro Russian Demonstrations In The Crimea Region

PEREVALNE, UKRAINE - MARCH 03: A Ukrainian soldier stands inside the gate of a Ukrainian military base as unidentified heavily-armed soldiers stand outside in Crimea on March 3, 2014 in Perevalne, Ukraine. Scores of heavily-armed soldiers not displaying any idenifying insignia have taken up positions outside the base and parked several dozen vehicles, mostly trucks and patrol cars, nearby. Their commander has reportedly told the Ukrainian unit to hand over the base and come out without any weapons, though the Ukrainians have thus far refused. Soldiers have surrounded several Ukrainian military bases across Crimea in recent days as pro-Russian forces are cementing their seizure of authority in the peninsula.
