Typhos Runganga said he watched helplessly as the aircraft caught fire and crashed into a building.

Images from the site showed the plane broken into several pieces.

Survivors say they believe the crash was as a result of an engine failure.

The plane was on a test flight before it was due to be flown to the Aviodrome air museum in the Netherlands via stops in east Africa, Egypt, Croatia and Austria.
