The latest count on Al-Jazeera was 109 with over 800 wounded, and reports of 40 bodies bulldozed away that no one can reach. They did shoot at a crowd of thousands.
Let's not split hairs between dead or wounded. Getting wounded while starving and no hospitals functioning and everyone around you has dysentery dooms someone to a very slow, very painful death.
They're shooting to kill. If they hit someone, that person has been gunned down whether they die immediately or after bleeding out. They're shooting at a crowd of thousands, and 800 are dead or dying as a result, according to Al Jazeera. So maybe we need to wait a few more hours before the 1000+ number can be confirmed, but it's already obvious Israel was aiming for 'thousands'.
