Golders Green attack claim highlights rise of shadowy Iran-linked group

HAYI has taken responsibility for a string of incidents targeting Jewish sites, but investigators say the latest claim may be opportunistic rather than state-backed

• Police treating stabbing of two men in Golders Green as terrorism

It took just over an hour after the horrific knife attack on two British Jewish people in Golders Green, north London, for an Iran-linked terror group, Harakat Ashab al-Yamin al-Islamia (HAYI), to make a claim of responsibility on a Telegram channel.

Counter-terror police are aware of the initial posting - a brief statement accompanied by the group's logo - put online at 12.23pm and a follow-up 40 minutes later showing a violent attack at a bus stop.
