Ajax, like Spurs, are known as a 'Jewish' club for various reasons. The attacks on Israelis seem to have taken place outside the stadium, apparently involving groups of Arabs.
Ironic that some of those vehemently decrying attacks on innocent Palestinians are disgustingly cheering this attack on Jews, just for being Jews, who may have all sorts of varying views on what's happening in Gaza & Lebanon. Some of you are utterly abhorrent.
If Bluemoon had been around in the 1930's, the aftermath of Kristallnacht would have been interesting.
