Rust is a very slow reaction. You can't just set a fire and get rust.
But what you can get with a good fire is most of the paint burnt off the vehicle.
There still seemed to be a lot of paint on the ambulance, though the paint was showing its age.
Sorry, Oralloy, but you are incorrect. May I suggest you do a little experiment. Take a piece of unpainted iron and put it in a furnace for a very short while, then leave to cool in the open air and you will see that a thin layer of rust forms quite quickly. Have you never made campfires as a kid and seen how iron that was in the fire becomes red with rust soon after you put the fire out.
An explosion causes a flash of extreme heat, which will affect the iron of a car where it has been exposed to the air (because the paint was knocked off by the shrapnel piercing the roof in this example). It does not last long enough to burn the lacker off a car since that is pretty resistant.
Finally I totally disagree with you that the paint on the ambulance was old. When a coat of lacker deteriorates it will affect first the areas most exposed to stress like the rims of the doors (look at the door, the paint is in pristine condition as it is everywhere on the vehicle except where it was hit by the exposion).
Summing up, what this picture shows me is a Lebanese ambulance (see the undamaged vehicle of the same type) that was damaged by an airburst of some kind that occurred fairly recently (as, for example, the broken blue light shows, the parts hanging out have not had time to deteriorate). The explosion took place above, slightly behind and to the right of the vehicle, judging from the direction the bent sides of the holes indicate.
FYI: The picture was taken by a ICRC photographer (J Bjorgvinsson) and the caption reads: One of two Lebanese Red Cross ambulances hit in southern Lebanon.
