FRANKFURT, July 7 (Reuters) - Deutsche Lufthansa's

Swiss International Airlines said on Monday that a

Zurich-bound flight from Belgrade made an unscheduled landing in

Friedrichshafen, Germany, because of light smoke in the rear

section of the aircraft's cabin.

The landing was "uneventful", and buses are being arranged

to transport passengers onward to Zurich, said Swiss, adding the

cause of the incident with the Airbus A220 was under

investigation.
