The EU's aviation regulator has warned airlines of the potential danger of flying over Iran, Iraq, and the Caspian Sea after Russia fired cruise missiles at Syrian targets.
The European Aviation Safety Agency (EASA) noted the launch of missiles from warships in the Caspian Sea in its safety bulletin issued on October 9.
The EASA said it had no specific recommendations right now, but was issuing the bulletin to inform airspace users about the potential hazard.
Air France said it had made adjustments to take the warning into account.
A spokesman for Lufthansa told Bloomberg the German airline had made no changes to flight paths across the region given the available information.
Russia said on October 7 that it was using warships in the Caspian Sea to target the Islamic State group in Syria.
