The crisis in Ukraine took another ominous turn Friday when gunmen in unmarked military uniforms took control of two airports on the Crimean peninsula — where the majority of people are ethnic Russians and many want to break away from the new government in Kiev.
There was no violence. No shots were fired. But Ukraine's new interior minister, Arsen Avakov, wrote on his Facebook page that "military units" from the Russian Navy fleet based at Crimea's Black Sea port of Sevastopol were at one of the airports. At the other airport, Avakov wrote, the men "[did] not hide their affiliation to the armed forces of the Russian Federation."
Avakov's claims were dismissed by Moscow. "Russia's Black Sea Fleet has denied that Russian servicemen are taking part," the BBC says.
In the mid-afternoon (early morning in the U.S.) there was also word from Reuters that "more than 10 Russian military helicopters flew from Russia into Ukrainian airspace over the Crimea region on Friday," Reuters reports.
