Aviation officials in Nepal say a plane carrying tourists to view Mount Everest has crashed, killing all 19 people on board.

Authorities say one passenger initially survived the crash Sunday, but died later in a hospital.

Officials say the plane crashed in heavy fog, a few kilometers south of Katmandu.

Aviation authorities say the Buddha Air Beechcraft had taken the tourists to view Mount Everest and other high peaks and was returning to Katmandu when it crashed.

The popular “mountain flights” take tourists over the Everest region where passengers can view some of the world's highest peaks from the airplane windows.
