French prosecutors have linked a foiled attack on a Bank of America branch in Paris to a pro-Iranian group, according to a joint statement from the Paris anti-terrorism office and the DGSI, France's domestic intelligence agency. Three suspects were detained in coordinated raids across the Île-de-France region early Wednesday morning. Authorities recovered what they described as "significant materials" from two locations.

The planned attack, which sources say targeted the bank's operations center in La Défense, was reportedly in its final stages of preparation. Investigators believe the cell had been active for at least four months, with communications traced to contacts in Lebanon and Iraq.

A senior French intelligence official, speaking on condition of anonymity, told reporters that the suspects had "clear ideological alignment with Iranian-backed networks," though Tehran has not been formally named in the investigation. The Iranian embassy in Paris declined to comment.

The foiled plot comes at a time of deepening tension between Paris and Washington over the ongoing US-Israeli military campaign against Iran. France has repeatedly refused American requests to open its airspace for military operations, a position that has drawn sharp criticism from the White House and strained a decades-old alliance.

Just last week, French President Emmanuel Macron reaffirmed that France would not "become a corridor for a war we did not choose and do not support." The US State Department responded by calling the decision "deeply disappointing" and warned of "consequences for the broader security relationship."

European security analysts have been warning for weeks that the Iran conflict would generate blowback on the continent. The Strait of Hormuz blockade has already sent oil prices past $130 a barrel, and European capitals are scrambling to manage both the economic fallout and the growing threat of retaliatory operations on their soil.

"The pattern is not complicated," said Jean-Pierre Filiu, a professor of Middle East studies at Sciences Po in Paris. "When you wage war on a country with a global proxy network, the battlefield does not stay in one place. It never has."

France is not the only European country on alert. Germany and Belgium have both raised their threat levels in recent weeks, and the UK's MI5 has reportedly activated additional surveillance protocols around American corporate and diplomatic targets on British soil.

Meanwhile, the three suspects in custody in France are expected to face formal charges by Friday. Prosecutors have requested an extension of their detention to 96 hours under France's anti-terrorism statutes, which allow for longer pre-charge holding periods.

For France, the timing raises uncomfortable questions. A nation that has positioned itself as the leading European voice against the Iran war now finds itself dealing with the very kind of threat that Washington has warned about — and one that critics will inevitably use to argue that Paris should have fallen in line.

Whether the foiled attack and France's airspace refusal are connected is a question that French intelligence is reportedly examining closely. What is not in question is that the war in Iran is no longer something that happens "over there." It is here. And it is only the beginning.
