Oh, people are arguing about exactly that. We’re even in a subthread which is all about the number 500!

Now, who has a rocket that can kill hundreds of humans
As far as I know, all evidence points to a palestinian device, including the small blast radius.
And the claim that “hundreds of humans” were killed is most probably fake news.
I’m not interested to go into further rabbit holes. This cannot be resolved in debate anyways. Future investigations might reveal what happened, we cannot do that here.
