Things we know:
Mark Regev, Israeli spokesman said "Israel does not target hospitals"
Israel told several hospitals in Gaza to evacuate, including this one. This can only be because they intended to target it.
The Israeli Digital Media spokesman posted a tweet saying IDF had struck the hospital, then deleted the tweet when news of mass casualties came in.
Prior to this bombing, Hamas rockets that have hit targets have done very little damage.
We are being asked by the people who have been bombing Gaza to believe that they didn't bomb Gaza.
