Iran's Deputy Foreign Minister Majid Takht-Ravanchi declared European Union member states joining U.S. and Israel in attacks against Iran would become "legitimate targets" for retaliation. The threat escalates tensions as some EU countries including France, Greece and Italy have already deployed warships to the region following Iranian strikes.

Most EU officials have condemned Iranian attacks while calling for diplomatic solutions. German Chancellor Friedrich Merz confirmed Berlin is working with partners to end the fighting, though his country shares objectives with the United States and Israel. The Iranian statement creates uncertainty for international businesses operating in the region.

The development adds geopolitical risk to global markets, particularly affecting energy prices given Iran's role as a major oil producer. Companies with operations in Middle Eastern or European markets face increased security concerns and potential supply chain disruptions as the diplomatic situation deteriorates.
