As escalating tensions in the Middle East ripple into Europe, Germany’s domestic intelligence agency has raised the alarm over a growing threat from Iran-linked terrorist networks, prompting Jewish communities to heighten security amid fears of targeted attacks.

On Tuesday, the German Federal Office for the Protection of the Constitution warned of a rising threat level across the country and Europe more broadly from pro-Iranian extremist groups, specifically citing the expanding activities of Harakat Ashab al-Yamin al-Islamiya and signaling broader concerns about coordinated operations on the continent.

“What’s new is [the terrorist group’s] warning that they will no longer limit themselves to ‘simple’ attacks but will also include more dangerous means in the long term,” an agency spokesperson told the German newspaper Handelsblatt, pointing to an apparent shift toward more sophisticated and potentially lethal methods, including the use of explosives or weapons.

Since the start of the US-Israeli campaign against Iran earlier this year, European governments have tightened domestic security amid mounting fears that Tehran could activate proxy networks across the continent to retaliate against US, Israeli, and Jewish targets.

But even with increased security and heightened intelligence monitoring, Europe has seen a string of attacks targeting Jewish and Israeli institutions, several of them claimed by the newly emerged Iran-linked terrorist organization.

Just in April, Harakat Ashab al-Yamin al-Islamiya claimed responsibility for a wave of attacks across the UK, Germany, North Macedonia, Belgium, and the Netherlands, many of them concentrated in London.

Since emerging in early March, the group has taken credit for at least 15 attacks against Jewish and Western targets across Europe.

German intelligence has identified a recurring pattern, with young individuals repeatedly recruited via social media and encrypted platforms to carry out attacks in exchange for modest payments.

German officials suspect the terrorist group may be part of a broader Iraqi Shiite network with ties to Iran’s regional proxy infrastructure, raising concerns about cross-border coordination and external direction.

“The organization uses various channels from the Shiite extremist and pro-Iranian sphere on different social media platforms to report on its activities,” the agency said in a statement. 

“The group has also recently stated its political motivation behind its actions and openly threatened Israeli institutions as well as the so-called ‘enemies of Islam’ in Europe,” it continued.

In recent weeks, six sites across Greater London have been targeted, including a Jewish ambulance service and a Persian-language media outlet. In the latest incident on Saturday, an accelerant-filled bottle was hurled through the window of a synagogue in Harrow, on the outskirts of London.

Marc Henrichmann, who chairs the parliamentary oversight committee of Germany’s intelligence services, told Handelsblatt that the surge in incidents is “closely linked to the escalation of the Iran conflict,” warning that the spillover is already being felt across Europe as alarm grows among security experts.

“The threat to Jewish, Israeli, and American institutions remains high, even though they are already under special protection,” Henrichmann said.

“Our objective must be clear: to identify and dismantle these foreign-controlled terrorist networks, and to do so we must significantly strengthen our intelligence capabilities, particularly in the digital domain,” the German official continued.
