BERLIN (AP) — The European Aviation Safety Agency has issued a safety bulletin to airlines and authorities regarding Iranian and Iraqi airspace after Russian warships in the Caspian Sea last week fired cruise missiles toward Syria.

EASA said in a bulletin dated Friday that "before reaching Syria, such missiles are necessarily crossing the airspace above (the) Caspian Sea, Iran and Iraq, below flight routes" used by commercial aircraft.

The agency says it has no specific recommendations at this point and was issuing the bulletin to inform airspace users about the potential hazard. EASA said it will be amended "if more specific information is received" about the situation.

Russia said on Wednesday that it was using warships in the Caspian Sea to target the Islamic State group in Syria.
