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'.

Also is this the same event?
