EU chief Ursula von der Leyen said on Friday she was "outraged" by "vile attacks targeting Israeli citizens in Amsterdam" after clashes following a football match led to arrests and hospitalisations.

"I strongly condemn these unacceptable acts," von der Leyen wrote on social media X 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."

The United Nations said Friday it was deeply troubled by the clashes in Amsterdam surrounding a football match between hosts Ajax and Israeli side Maccabi Tel-Aviv, violence branded "anti-Semitic" by Israeli and Dutch leaders.

"We have seen these very troubling reports," UN human rights office spokesman Jeremy Laurence told a media briefing in Geneva, adding: "Nobody, nobody should be subjected to discrimination or violence on the basis of their national, religious, ethnic or other origin. We understand that the authorities have launched an investigation into this incident."

Five people have been hospitalised and 62 arrested as a result of clashes that erupted in Amsterdam overnight following a football match, police said on Friday.

"Several reports about last night’s events in Amsterdam are circulating on social media," Amsterdam police said in a post on X.

"So far, it is known that five people have been taken to the hospital and 62 individuals have been arrested."

"The police have launched a major investigation into multiple violent incidents," it said.

"The police are aware of reports regarding a possible hostage situation and missing persons but currently have no confirmation that this actually took place. This aspect is also under investigation," it said.

The violence flared in Amsterdam after the game between Maccabi Tel-Aviv and home team Ajax, which won 5-0.

Israeli and Dutch leaders have condemned the "anti-Semitic" violence and Israel has sent "rescue planes" to bring the football fans home.
