(CNN) -- Commercial airlines that usually cross eastern Ukraine on their flights to Europe, Asia and elsewhere are detouring away from the volatile region in light of Thursday's suspicious crash of Malaysia Airlines Flight 17. The Federal Aviation Administration said Thursday that U.S. airlines had voluntarily agreed not to operate in airspace near the Russian-Ukraine border. Later, the FAA issued a notice prohibiting U.S. flight operations in the airspace over eastern Ukraine until further notice. The restricted area includes the Dnepropetrovsk and Simferopol Flight Information Regions. The European Aviation Safety Agency and intergovernmental aviation organization Eurocontrol also warned against flying in these areas.
