AMSTERDAM (AP) — Antisemitic rioters “actively sought out Israeli supporters to attack and assault them” after a soccer match, Amsterdam authorities said Friday as Israel said it was sending planes to the Dutch capital to fly fans home.

An unknown number of Israeli supporters were injured in the Thursday night violence that was condemned by the leaders of both the Netherlands and Israel as antisemitic.

A statement issued by the Dutch capital’s municipality, police and prosecution office said that the night after the Europa League match between Ajax and Maccabi Tel Aviv “was very turbulent with several incidents of violence aimed at Maccabi supporters.”

There was no immediate word on the number of injured or arrests.

The violence erupted Thursday despite a ban on a pro-Palestinian demonstration near the soccer stadium imposed by Amsterdam Mayor Femke Halsema, who had feared that clashes would break out between protesters and supporters of the Israeli soccer club.

Israel ordered that two planes be sent to the Dutch capital to bring the Israelis home.

“The Prime Minister has directed that two rescue planes be sent immediately to assist our citizens,” said a statement from Benjamin Netanyahu’s office.

It added that “the harsh pictures of the assault on our citizens in Amsterdam will not be overlooked,” and that Netanyahu “views the horrifying incident with utmost gravity.” He demanded that the Dutch government take “vigorous and swift action” against those involved.

Netanyahu’s office added that he had called for increased security for the Jewish community in the Netherlands.

Dutch Prime Minister Dick Schoof said on X that he followed reports of the violence “with horror.”

“Completely unacceptable anti-Semitic attacks on Israelis. I am in close contact with everyone involved,” he added, saying that he had spoken to Netanyahu and “emphasized that the perpetrators will be tracked down and prosecuted. It is now quiet in the capital.”

Geert Wilders, the hard right nationalist lawmaker whose Party for Freedom won elections in the Netherlands last year and who is a staunch ally of Israel, reacted to a video apparently showing a Maccabi fan being surrounded by several men.

“Looks like a Jew hunt in the streets of Amsterdam. Arrest and deport the multicultural scum that attacked Maccabi Tel Aviv supporters in our streets. Ashamed that this can happen in The Netherlands. Totally unacceptable,” Wilders said.

Israel’s Ambassador to the United Nations, Danny Danon, also condemned the violence in a post on the social media platform X.

Ajax won the Europa League match 5-0.
