This source is a bit questionable. Wikipedia says it is very pro-Israel and has in the past published articles from a fabricated reporter. Their own "about us" page also says their executive editor was formerly with Fox News. This is enough for me to be sceptical. I couldn't find a local article but this article says the victims did not file a police report.
I'm not saying this didn't happen and I do believe there are some antisemites using legitimate criticisms of Israel as a screen but there's a lot of propaganda out there and we should be mindful of spreading unverified information.
I've noticed this sort if thing becoming more common and I think it is very much related to bots scraping the web. I'm sure they'll be happy to sell access to that data though.
