Military presence descends on 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. (Getty)
