The last one was so packed with weapons and explosives that there were not one but two secondary explosions after it was hit...

... and you can be quite confident that when the video comes out for this one you'll see the same thing:

As Israel's Operation Cast Lead against Hamas in Gaza entered its sixth day, the Israeli Air Force bombed a mosque in the village of Jabalya in the northern Gaza Strip. The Holfe Mosque was used as a launching ground for rockets, a meeting place for Hamas terrorists, as well as storage facility for arms and a communications center.

The IDF press release on the attack describes "numerous secondary explosions" and points out that Hamas was launching missiles from the roof. Hospitals, schools, and holy places - say what you will about Hamas but it's undeniable that they're completionists.
