Passengers on an Iran Air flight learned the hard way why you should keep your seat belt securely fastened while taxiing after their plane collided with a truck loaded with jet fuel.

Details are a little limited at this point, but what we know from friend and photographer Mokhtar Chahine is that the incident happened at the Jeddah Airport in Saudi Arabia. The tail number and insignia clearly identifies it as an Iran Air jet.

Based on the tipped nature of the refueling truck it looks like the plane crashed into the truck and not the other way around. In the event of an explosion, please proceed to the exit that suddenly opens over the left side of the plane.
