Russian Fighter Jets Patrolling Ukraine Border

Russia sent fighter jets to patrol its border with Ukraine on Thursday, as fast-paced developments threatened to undermine the new Ukrainian government in Kyiv.
Gunmen seized control of government buildings in Crimea, a Ukrainian region with strong ties to Moscow and home to a Russian naval base in Sevastpol. The gunmen raised the Russian tri-color flag.
While Russian jets soared through the skies in military exercises ordered by President Vladimir Putin, U.S. Defense Secretary Chuck Hagel warned Moscow to not take any action on Ukraine that could be misinterpreted.
Crimea has been the scene of confrontations between supporters of Ukraine's new government and pro-Russia activists.
