Ukraine’s new government declares Russia has invaded

"Ukraine’s new government declared on Friday that it had indeed been invaded, as gunmen in matching fatigues seized control of the two main airports in the southern region of Crimea and troop trucks with Russian license plates were seen moving around the peninsula. Ukraine’s border service also reported an airspace incursion by at least 10 Russian military helicopters, an accusation that seemed to be supported by amateur video, and there were reports of movements by Russian transport planes and warships."
