More ominous developments in Crimea: Armed men have blockaded two airports in the peninsula, a day after pro-Russian gunmen took control of the regional parliament building. There are conflicting reports on who the airport gunmen are and whether they have actually taken control of the airports. At the airport in Simferopol, the Crimean capital, dozens of gunmen in unmarked military uniforms have been seen patrolling the area. "We are checking to make sure that no radicals come to Crimea from Kiev, from the Ukraine," one gunman told reporters. Flights there appear to be operating normally, CNN finds, but the Wall Street Journal reports that the other airport, Sevastopol's Belbek Airport, has been closed. Ukraine's interior minister blames Russian military units, calling this "a military invasion and occupation," the AP reports.
