How do we know Jews were stoned and injured Monday night?

Because a Hamas website tells us so!

Hamas' Palestine Times quotes Israel radio as saying that Jews were injured by stones thrown by Palestinian Arabs on Monday night near Qaryut, which appears to be near Shiloh. I can find nothing about this on any other website.

I guess that there aren't armies of international observers with cameras around to document Arab violence when Jews are the targets. And if they had witnessed it, they sure wouldn't admit it.
