Air operators should not operate within Iranian airspace, the European Union Aviation Safety Agency (EASA) warned in an advisory released on Friday evening. EASA wrote that there is a high likelihood of misidentification within Iranian airspace and that the possible response of Iranian defense systems to a perceived attack could prove dangerous to civil flights.

"Given the ongoing situation and the potential for US military action, which has placed Iranian air defence forces on a heightened state of alert, there is currently an increased likelihood of misidentification," EASA wrote.

'Implement contingency planning,' EASA instructs

EASA also warned air operators to "exercise caution and implement contingency planning" for any flights within the airspace of neighboring countries, particularly those that contain US military bases.

"In the event of a US intervention, the possibility of retaliatory actions against its assets in the region cannot be excluded, which could introduce additional risks to the airspace of neighbouring countries where the US military bases are located," the advisory warned.
