French authorities are investigating a suspected link to Iran after foiling a bomb attack outside a Bank of America building in Paris over the weekend, in one of the latest terrorist plots to heighten fears of further Iran-linked attacks across Europe amid war in the Middle East.

On Monday, French Interior Minister Laurent Nuñez confirmed investigators are looking into a possible connection to Iran, citing similarities between the foiled attack and a string of recent attempted terrorist plots across Europe claimed by a pro‑Iran group.

“Authorities are drawing a direct link to Iran, since the modus operandi mirrors attacks recently carried out in the Netherlands and Belgium,” Nuñez told the French radio station RTL, referring to a synagogue set ablaze in Rotterdam and another damaged in an explosion in Liège earlier this month.

Known as Harakat Ashab al-Yamin al-Islamia, which translates to the Islamic Movement of the Companions of the Right, the group has also taken responsibility for a shocking attack in London last week, torching four ambulances belonging to a Jewish community organization.

Although no government has formally acknowledged or verified the existence of the group or its alleged operations, the repeated claims have raised concerns about a potentially coordinated network targeting Jewish communities across Europe amid heightened tensions and fears of Iranian retaliation and possible sleeper-cell activity linked to the war in the Middle East.

In this latest incident, local police in Paris spotted two suspects on Saturday near the Bank of America building in the city’s 8th arrondissement — a central district near major government offices and embassies — just moments after they had planted a homemade explosive device, with one of the men preparing to ignite it with a lighter.

Shortly after authorities thwarted the attempted attack, France’s anti-terrorism prosecutor’s office opened an investigation for “attempted damage by fire or dangerous means in connection with a terrorist enterprise.”

Since then, five suspects — including three minors and two adults — have been arrested on alleged terrorism-related offenses as investigators work to determine whether the plot was coordinated from abroad and linked to a wider network.

According to French media reports, the suspects were recruited via Snapchat and offered 600 euros to carry out the operation — a tactic officials say reflects a modus operandi increasingly used by Iranian intelligence services to operate indirectly and discreetly without formally implicating Tehran.

“Typically, Iran’s intelligence services operate in this way: They use proxies, a series of subcontractors, often common criminals, to carry out highly targeted actions aimed at US interests, the interests of the Jewish community, or Iranian opposition figures,” Nuñez said.

As the US–Israeli war with Iran continues to escalate, Nuñez also said authorities have dramatically ramped up security around key figures and sensitive sites, including providing personal protection to some Iranian opposition members.
