Some crater shots.

Based on available evidence, it appears the explosion happened in a courtyard which is part of the hospital site. Images of the ground after the blast do not show significant damage to surrounding hospital buildings. What the images do show includes scorch marks and burnt-out cars.

The Israel Defence Forces (IDF) say that the absence of a large crater, or blast damage to adjacent buildings, proves that the explosion was not caused by its weapons.

Another important part of missing evidence is missile fragments. Projectiles are often identifiable by the wreckage of their shell, and they can be used to determined the projectile's origin. But in this case, we have not seen that evidence.
