Counter-terrorism police are investigating an online claim by a suspected terror group taking responsibility for the attack on four Jewish community ambulances.

A Telegram post from Harakat Ashab al-Yamin al-Islamia in which it claims to be behind the arson has circulated online and was shown to the Press Association by a member of the Jewish community at the scene in Golders Green, north-west London.

An unverified video posted at 6.13am on Monday on its Telegram channel showed street view Google Maps images of the ambulances and footage of explosions.

At the start of the video posted on Telegram, a message in English said the group’s primary target was the Machzike Hadath Synagogue due to its links to Israel.

The post also cited Conservative former prime minister Rishi Sunak’s visit to the synagogue during the election campaign in June 2024 to express “his country’s unwavering support for Israel”.

Harakat Ashab al-Yamin al-Islamia, which translates to the Islamic Movement of the Companions of the Right, is a new terrorism group with suspected links to pro-Iranian networks, according to Israel’s Ministry for Diaspora Affairs and Combating Antisemitism.

The group previously claimed responsibility for several attacks on Jewish sites in Belgium and the Netherlands between March 9 and March 14, according to the Israeli ministry.

They included an explosive attack at a synagogue in Liege, Belgium, an arson attack on a Rotterdam synagogue and an explosive device set off at a Jewish school in Amsterdam.

The group’s Telegram channel, which was apparently only created on Saturday, also includes a video of an attack in Amsterdam targeting an American bank.

Harakat Ashab al-Yamin was also suspected to be linked to an attack at a Jewish site in Greece, according to the Israeli diaspora ministry.

Israel’s Ministry of Foreign Affairs posted on X on March 15 that “a jihadi group tied to an Iranian proxy” was responsible for the attacks.

It said “the IRGC continues to sponsor and export terror across the globe”.

Earlier in March, the Israeli diaspora ministry released a report which said the attacks appear to be part of intimidation and psychological warfare against Jewish communities in Europe.

Diaspora affairs and combating antisemitism minister Amichai Chikli was quoted by The Times of Israel and others as saying: “The recent events in Europe are not isolated incidents but part of a disturbing pattern of action: Terrorist networks affiliated with the Iranian axis are trying to expand their arena of operation into the cities and Jewish communities of Europe.”

The report also said that the group operates through local cells or individuals who are directed from abroad.

It highlighted that the organisation’s name is similar to one used by the Iraqi militia Harakat Ansar Allah al-Awfiya, which was described as a terrorist organisation by the US State Department.

The group’s logo also closely resembles the symbols used by Iranian-aligned militant groups, according to The Times of Israel.

Metropolitan Police Detective Chief Superintendent Luke Williams said: “We are aware of an online claim from a group taking responsibility for this attack.

“Establishing the authenticity and accuracy of this claim will be a priority for the investigation team but it is not something we can confirm at this point.”
