It is impossible to ever know, but it would be interesting if we could find out how many of these 60+ terrorists were killed by other terrorists. Imagine the weapons safety nightmare of having a mass crowd of armed crazy Muslims. What better time to settle up feuds, or to take out the fiance' of some girl you want to marry.
You give one of these crazy monkeys an automatic weapon and he will shoot anybody. He doesn't care who they are. Muslim or Israeli are all the same to a terrorist. When these guys blow up a bus, or an airplane, or a mall, they don't give one single damn how many Muslims they kill as long as they are able to hit the Infidels. Hamas terrorists are willing to kill their own parents, their brothers or sisters, their sons or daughters, their neighbors or strangers, even themselves. So it would be nothing for them to shoot their fellow rioters in order to raise the body count.
I'm sure only a small percentage of these 60 killed were actually shot by Israelis. And if they were shot by the IDF, it means that they presented an imminent fatal deadly threat to Israeli troops. That is the only way they would use lethal fire.
