I had to read past the fold to discover that it wasn't just empty accusations, it was investigated and confirmed by UNRWA internally:
> The agency has acted in response to Israel’s accusations. UNRWA this year has fired 13 employees, including nine whom an oversight body determined may have been involved in last year’s Hamas attack based on evidence provided by Israel.
Honestly that seems kind of important for potential donors to know? Good on UNWRA for investigating the issue and dealing with it, but it's also strange that this situation happened at all
Israel has over the years investigated and found guilty a number of its citizens as guilty of crimes against Palestinians - nothing surprising about that, in any large community you'll find criminals.
But imagine UNRWA was spending its budget on AdWords that link from "Israel" to a list of such crimes. I think that would leave a similarly bad taste.
