French President Emmanuel Macron said Tuesday night that the U.S.-Israeli strike on Iran that killed the country’s supreme leader was carried out “outside of international law,” adding that France cannot support the operation.

In a nationally televised address, Macron placed responsibility for the broader conflict in the Middle East on Iran but made clear that Paris does not endorse the strikes themselves, a stance that could strain relations with Washington.

His comments come as tensions between the United States and some European governments have intensified over the war. Earlier Tuesday, President Donald Trump threatened to halt trade with Spain after Spanish Prime Minister Pedro Sánchez condemned the war as illegal and refused to allow American military aircraft to operate from Spanish bases during attacks on Iran.

German Chancellor Friedrich Merz, who appeared alongside Trump during the press conference where the trade warning was issued, did not publicly defend Sánchez at the time. Macron’s remarks now appear to place France closer to the Spanish position regarding the legality of the conflict.

Although Trump has suggested the fighting could conclude within days or weeks, Macron warned that the conflict may continue for an extended period.

“Strikes will likely continue in the coming days to weaken Iran and destroy its counterattack capabilities. And in response, Iranian strikes in the whole region are expected to continue,” Macron said.

Macron also announced that France is strengthening its military posture in the region to safeguard its interests. The French aircraft carrier Charles de Gaulle is being deployed to the Mediterranean, accompanied by fighter jets and air-defense systems.

“We will continue this effort as long as it is needed,” he said.

The French president confirmed that Paris has also dispatched anti-missile defense systems to Cyprus, a move that had previously been reported.

“Cyprus, an EU member state, a country with which we have signed a strategic partnership … requires our support,” he said.

Macron stressed that France must uphold its credibility by honoring its security commitments to allies in the region, including Qatar, Kuwait, and the United Arab Emirates, where approximately 800 French troops are currently stationed.

On Sunday, Iranian drones struck a French naval facility in the United Arab Emirates, though no casualties were reported.

French fighter jets also conducted flights over the UAE during the weekend as part of what officials described as “sky security operations,” according to French Foreign Affairs Minister Jean-Noël Barrot.
