Report of potential Iranian strikes on US targets in Europe

The Financial Times reported on Wednesday that Iran has considered striking US military targets in Europe if President Donald Trump escalates the war. Citing two people close to the Iranian regime, the report said Iranian forces have assessed potential strikes against US assets in southeastern European countries, including Bulgaria, where the parliament last month approved the use of the Bezmer air base for US refuelling aircraft. Cyprus was also named as a potential target, with one insider noting that a British air base on the island was struck by a drone in March.

The report, carried by multiple outlets, said Iranian forces have separately examined attacking subsea fibre-optic cables in the Strait of Hormuz in the event of an escalation. The threats reflect a defiant mood in Tehran, where many within the regime increasingly see a resumption of the war as a matter of when, not if.

NATO and allied responses

A NATO official said in a statement on Wednesday: "NATO is prepared to address any threat and will always do what is necessary to defend all Allies." The unnamed official added that NATO air defences intercepted four ballistic missiles Iran launched towards Turkey this year, offering it as proof that the alliance's "deterrence defence posture is strong and effective." The remarks were in response to the Financial Times article, as reported by the Jerusalem Post and TASS.

Bulgaria has increased security measures at the Bezmer Air Base. Interior Minister Ivan Demerdzhiev told the country's BTA news agency that Bulgaria had taken "all possible measures" at the base in coordination with the Ministry of Defence, designed to address a threat level higher than currently indicated by security services. "We are constantly monitoring the situation and developments and will continue to take precautionary measures that are far more extensive and intensive than the level of threat indicated by the information available at the moment," he said, as reported by Al Jazeera.

Cyprus has also been taking steps to protect itself. "A competent source" told the Cyprus News Agency: "We have been taking enhanced precautionary measures for several months now. We are closely monitoring developments." The source added that four Greek Air Force F-16 fighter jets, as well as the Nikiforos Fokas frigate, are currently stationed in Cyprus.

However, sources at the Cypriot Foreign Ministry told the Cyprus Mail that the Financial Times' reports are inaccurate, noting that Cypriot diplomats are in contact with the Iranian government and convinced that "Cyprus is not a target." They also noted that similar claims have surfaced before.

Iran's warnings and internal dynamics

Iranian Foreign Minister Abbas Araghchi warned his Bulgarian counterpart that "any party that participates in any way in carrying out a military attack against Iran will certainly have to accept responsibility for its consequences," according to Iran's Tasnim News Agency, as reported by Al Jazeera. Araghchi also warned that any country aiding US "aggression" against Iran would be considered a legitimate target of retaliatory attack.

The Islamic Revolutionary Guard Corps and other military commanders have warned that in any new full-scale conflict, Iran would move beyond its previous strategy of attacking US military assets, energy facilities, and other infrastructure in the Middle East to targets farther afield. The guards last month threatened the UK over American use of British military bases, saying "any base that is used to launch an attack on Iranian territory will be considered a legitimate target," as reported by The Irish Times.

According to two regime insiders, Iran's retaliation would depend on Washington's actions. One insider said the regime was preparing a plan to expand the conflict were Trump to make good on previous threats to attack Iranian infrastructure. The second insider said Iran would place "no limits" on its response in the event of US aggression, and would "go beyond the region and hit Europe too."

Strategic context: Diego Garcia and regional escalation

The report comes amid heightened tensions and a stalled diplomatic track. A 60-day ceasefire between the United States and Iran expired on Monday, and Trump said on Tuesday that there are "no talks or conversations going on, or scheduled" with Tehran, as reported by The Irish Times and Al-Monitor. The June memorandum of understanding between the US and Iran fell apart after Tehran attacked vessels in the Strait of Hormuz, leading to tit-for-tat strikes and a renewed US blockade on Iranian ports.

The conflict has already seen Iran launch attacks on US and allied targets across the region. Iran retaliated for renewed US strikes with missile attacks on several countries not party to the conflict in the Gulf, and more recently Jordan. Turkey said in March that NATO air defences had downed a number of drones fired by Iran toward its territory.

The war has underscored the strategic importance of Diego Garcia, a joint US-UK military base in the Indian Ocean. The Pentagon shifted logistics to the remote base after an Iranian strike on a major American installation in Bahrain, according to Fox News — World. The US accused Tehran of launching several missiles toward Diego Garcia in March, roughly 4,000 kilometers from Iran; Tehran denied the accusations. Reports emerged in June that US officials had drafted a proposal to bypass Britain and strike a deal to take control of Diego Garcia, amid a broader sovereignty dispute over the Chagos Archipelago.

Expert assessments

Analysts offered mixed assessments of the threat. Sidharth Kaushal, a research fellow at the Royal United Services Institute, described the threat posed by Iranian missiles to targets in Europe as "real, but limited." Iran could deploy medium-range ballistic missiles like its Shahab series against US assets in southern and southeastern Europe, he said, but these would struggle to do damage at longer ranges. Douglas Barrie at the International Institute for Strategic Studies said the Diego Garcia strikes indicate Iran has weapons with ranges greater than 2,000 km, but questioned how many they hold and whether they would use them.

Ali Bakir, a senior non-resident fellow at the Middle East Council on Global Affairs, said an Iranian attack on Europe would play into Trump's hands and intensify Iran's isolation, and would likely benefit Russia's war in Ukraine. Angel Petrov, a Sofia-based journalist, said Bulgarians do not view the Iran war as important as Ukraine, and that Sofia lacks the institutional capacity to defy Washington while managing the war in Ukraine and an increasingly active Russia.

Some analysts suggested Tehran's threat may be more about signalling than action. An actual strike on a member of both the European Union and NATO would turn Europe from a hedging bystander into a belligerent party, trigger Article 4, and hand Washington the European coalition it has so far failed to assemble, according to an Al Jazeera analysis. Armida van Rij, a senior fellow at the Centre for European Reform, said southeastern Europe could be seen as an attractive target, calling it "the soft underbelly of Europe."

The longevity of the conflict is arguably a greater threat to Europe than Iranian missile capabilities that NATO defences could well protect against, the analysis added.
