text: Unidentified gunmen wearing camouflage uniforms guard the entrance to the military airport at the Black Sea port of Sevastopol in Crimea, Ukraine, Friday, Feb. 28, 2014. Russian troops took control of the two main airports in the strategic peninsula of Crimea, Ukraine's interior minister charged Friday, as the country asked the U.N. Security Council to intervene in the escalating conflict. Russian state media said Russian forces in Crimea denied involvement. No violence was reported at the civilian airport in Crimea's capital of Simferopol or at the military airport in the Black Sea port of Sevastopol, also part of Crimea. At the Simferopol airport, a man claiming to speak for the camouflage-clad forces patrolling the airport described them as Crimean militiamen. (AP Photo/Ivan Sekretarev
