Lufthansa flight to London Heathrow has turned around and is returning to Frankfurt.
The Airbus A320neo (registration D-AINV) departed Frankfurt Airport at 14:11 CEST to London Heathrow.
But while on approach to London, about 20 minutes before landing, the aircraft climbed back from 18,000 feet altitude and turned around for a reason unknown.
The flight will land back to FRA Airport about 2 hours after departure.
