NATO's top military commander said on Sunday that Russia had built up a "very sizable" force on its border with Ukraine and Moscow may have a region in another ex-Soviet republic — Moldova — in its sights after annexing Crimea.
Russia was acting more like an adversary than a partner, NATO's Supreme Allied Commander Europe, U.S. Air Force Gen. Philip Breedlove said, and the 28-nation alliance should rethink the positioning and readiness of its forces in Eastern Europe.
Russian troops, using armored vehicles, automatic weapons and stun grenades, seized some of the last military facilities under Ukrainian control on Saturday in Crimea, the Black Sea peninsula that Russian President Vladimir Putin formally annexed the day before.
