Australian airline Qantas said on Saturday it would redirect its long-haul flights between Perth and London to avoid Iran’s airspace amid soaring Middle East tensions.

A Qantas spokesperson told AFP the airline would temporarily adjust the flight paths due to “the situation in parts of the Middle East”.

“We’ll reach out to customers directly if there’s any change to their booking,” the spokesperson said.

The Perth-London flight, which is usually a non-stop 17-and-a-half hour journey, will now stop in Singapore to refuel, allowing it to carry a full load of passengers on an alternate route.

The return service — London to Perth — will continue to fly non-stop on a readjusted path due to prevailing winds.

All other flights are not affected.

The move comes after Iran blamed arch-foe Israel for a strike in Syria this month that killed two Iranian generals, and threatened reprisals.

Israel has stepped up strikes against Iran-linked targets in Syria since the onslaught in the Gaza Strip began in October.
