The door of a Jewish-owned shop in Hertfordshire was set on fire and vandalized with graffiti on Sunday in what police are treating as a religiously aggravated hate crime. Hertfordshire Constabulary said it is appealing for witnesses and reviewing possible security footage as part of the investigation.

Detective Superintendent Mark Clawson said authorities do not tolerate hate crime and are working to identify those responsible. Police are particularly seeking information about a group of young males seen in the area around the time of the incident.

Authorities said they do not currently believe the attack is linked to a recent series of arson attempts targeting Jewish, Israeli, and Iranian dissident-linked sites in London. However, the Campaign Against Antisemitism warned of a worrying rise in attacks on Jewish locations, noting multiple arson incidents over the past week, including firebomb attempts at synagogues, community buildings, and other sites.

A group believed to be an Iranian front organization has claimed responsibility for several of the recent attacks in London, though no claim had been made regarding the Hertfordshire incident as of Tuesday night.
