The Guardian has a story with the sequence of events and more video of multiple incidents. Maccabi (the Israeli team) supporters started burning Palestinian flags, vandalized a taxi, and started chanting about "let the IDF win, we will fuck the Arabs" and "there are no more children in Gaza."

Stuff like that went on for a while, police made a couple of arrests, then after the soccer match things got nastier. 5 people hospitalized (don't know who), Amsterdam natives demanding to know if people were Jewish and to see passports, Israeli supporters setting off fireworks and using makeshift weapons pulled from a construction site.

World leaders are calling it a targeted attack against Jews and shameful. No word in the article about leader reactions to what the Israelis did.

Edit for an important P.S. - Please don't lump all Jews into this. There are many Jews that are at least as fervent in their opposition to what's going on in Israel as any of us. Probably a lot more so because of the personal stakes. I think it's super important to support them because they're fighting from inside the culture. Israel does not equal all Jews - please don't be antisemitic.
