Armed Russian navy servicemen surround a Ukrainian border guard base in Balaclava, in the Crimea region February 28, 2014. Armed men took control of two airports in the Crimea region on Friday in what Ukraine's government described as an invasion and occupation by Russian forces, stoking tension between Moscow and the West. More than 10 Russian military helicopters also flew into Ukrainian airspace over the region on Friday, Kiev's border guard service said, accusing Russian servicemen of blockading one of its units in the port city of Sevastopol, where part of Moscow's Black Sea fleet is based.
