Egypt instructed all of its airlines to avoid Iranian air space for a three-hour period in the early morning on Thursday amid tension between Israel and Iran.

The NOTAM, a safety notice provided to pilots on Wednesday, said the instruction would be in effect from 0100-0400 GMT.

“All Egyptian carriers shall avoid overflying Tehran (Flight information Region) FIR. No flight plan will be accepted overflying such territory,” the notice said, referring to the three-hour period provided.

On Sunday, Jordanian authorities asked all airlines landing at its airports to carry 45 minutes worth of extra fuel.
