Excerpt:
"The lack of a large impact crater, and the limited damage radius, appears to suggest the weapon was not a bomb, as the thread by Nathan Ruser below explains. Ruser also offers evidence that the casualty numbers claimed by Gaza officials seem high relative to the structural damage visible and past truck bombings.
...
Photos of the aftermath show that the vast majority of the damage is from fire. Only 3 cars show any clear sign of kinnetic/structural damage. And for two of them, the general structure remains intact - despite clear damage.
Indeed, within 10m of the impact site there are cars which appear mostly undamaged."

Examine the speculation on how many could have been injured based on the damage location and spread. It appears that 500 casualties is impossible based on photos of the area.
Could this have been a Hamas propaganda effort after one of Hamas rockets being fired from nearby malfunctioned?
