Dramatic footage has emerged of a violent attack on a London synagogue.
A group of around 20 youths attempted to storm the Ahavas Torah building in Stamford Hill shouting "we will kill you all" in the early hours of Sunday morning.
Police say the attackers were drunk and had just left a nearby party. One of the congregation was punched in the face.
Six men have been arrested for public order offences and assault and one is reported to have made an anti-Semitic comment.
A police spokesperson said: "The incident is being treated as an anti-Semitic incident, due to remarks made by one of the group.
"However, there is nothing to suggest that it was a planned or targeted attack."
Rabbi Maurice Davis, of the Ahavas Torah synagogue, appeared to play down the attack.
He told the BBC: "I think this incident was more anti-social than anti-Semitic."
Inspector Jonathan Waterfield said: "We are investigating to establish the full circumstances of the incident and to identify anyone else involved in the disturbance who has not yet been arrested.
"We have also increased police patrols in the Stamford Hill area to provide reassurance to the community."
The Community Security Trust, which monitors anit-Semitic incidents, tweeted: "We are aware of alleged antisemitic assault at synagogue in Stamford Hill & are working w. Police & community. Suspects have been arrested."
Police urged anyone with information which might assist the investigation to call Haringey CID via 101.
