European Union Commission President Ursula von der Leyen says she’s “outraged” by “vile attacks targeting Israeli citizens in Amsterdam” after clashes following a football match led to arrests and hospitalisations, Al Jazeera reports.

“I strongly condemn these unacceptable acts,” von der Leyen wrote after speaking with Dutch Prime Minister Dick Schoof.

“Anti-Semitism has absolutely no place in Europe. And we are determined to fight all forms of hatred.”
