Not on settled public evidence. Recent reporting has raised fresh concern after Reuters said Iran fired two ballistic missiles toward the US-UK base on Diego Garcia, but Britain’s government said there is no assessment showing Iran is targeting Europe or that it has the proven capacity to do so. Publicly listed Iranian missile ranges from CSIS are still mostly shorter than what would clearly be needed to strike London or Paris directly from Iranian territory.
Iran’s missile capability is back in the spotlight because the debate is no longer only about Israel, Gulf states, or US bases in the region. Once reports emerged that Iran had fired missiles toward Diego Garcia, attention shifted fast to a harder question: if Tehran can stretch its reach farther than previously thought, could major European capitals be next? Reuters reported the attempted Diego Garcia strike on March 21, 2026, while the following day Reuters also reported that UK minister Steve Reed rejected claims that Iran is planning to strike Europe or has confirmed capacity to do so.
Why the question suddenly matters
The immediate trigger was the Diego Garcia incident. Reuters reported that Iran fired two ballistic missiles toward the joint US-UK military base in the Indian Ocean, with earlier reporting saying they did not hit the base. That matters because it suggested reach beyond the ranges most commonly associated with Iran’s best-known ballistic systems.
At the same time, Reuters reported that the Israel Defence Forces said Iran has missiles “that can reach London, Paris or Berlin.” Britain publicly pushed back. Steve Reed told the BBC, according to Reuters, that there was “no assessment” supporting that claim and that he was not aware of any assessment showing Iran was even trying to target Europe.
What the known missile-range data says
Public missile databases still show a more limited picture than the most dramatic headlines suggest. CSIS Missile Threat says Iran has the largest and most diverse missile arsenal in the Middle East, but its public list also places major systems such as the Shahab-3 at 1,300 km, Khorramshahr at 2,000 km, and Soumar at 2,000–3,000 km. CSIS adds that some Iranian systems can strike as far as eastern Europe, but it also says Iran has not yet tested or deployed a missile capable of striking the United States.
That means the cleanest answer is this: Iran is clearly dangerous at regional and near-regional range, but the public evidence is still not definitive that it has a reliable, operational missile capability to hit London or Paris. The reason the story is moving is that the Diego Garcia reporting suggests either an extended-range capability, a new workaround, or at minimum a fresh signal that analysts need to reassess what Iran may now be attempting. That conclusion is an inference from the public reporting and CSIS data, not a confirmed official UK assessment.
Could Iranian missiles reach Paris?
Possibly in theory, but not proven in settled public evidence. Paris is often mentioned in the same breath as London and Berlin because recent claims have pushed the debate from “regional threat” to “European reach.” But the UK government’s line, as reported by Reuters, is still that there is no assessment confirming that Iran can do this.
Could Iranian missiles reach London?
London looks even harder to state as a confirmed target on current public evidence. The UK government has not endorsed the claim that Iran can strike the British capital, and the best-known publicly listed missile ranges do not clearly settle the case. So a headline saying “Iran can definitely hit London” goes further than the currently published evidence supports.
What this means for Europe
Even without a confirmed Europe-strike assessment, the security meaning is serious. If Iran is testing longer-range options, improvising for extra reach, or trying to prove that it can threaten more distant targets, that changes the strategic picture for NATO governments. Europe may not be facing a confirmed immediate missile scenario, but the question is no longer hypothetical enough to ignore.
Final verdict
The most accurate conclusion right now is this:
Older public missile data does not clearly show Iran can strike London or Paris.
Recent reporting has raised new doubts after the Diego Garcia launch.
But Britain says there is still no assessment confirming Iran is targeting Europe or that it has the proven capacity to do so.
FAQ
Question: Can Iran currently hit London with missiles?
Answer: There is no settled public assessment confirming that Iran can currently and reliably hit London. Reuters reported that the UK government said there is no assessment proving Iran has that capacity.
Question: Can Iran currently hit Paris with missiles?
Answer: Public reporting has increased concern, but there is still no confirmed UK assessment saying Iran has proven capacity to strike Paris.
Question: Why are London and Paris being mentioned now?
Answer: Because Reuters reported Iran fired missiles toward Diego Garcia, and Israeli military messaging then claimed Iran has missiles that could reach major European capitals. Britain disputed that claim.
Question: What are the published ranges of Iran’s better-known missiles?
Answer: CSIS lists the Shahab-3 at 1,300 km, Khorramshahr at 2,000 km, and Soumar at 2,000–3,000 km, with some Iranian systems described as capable of reaching eastern Europe.
Question: Does this mean Europe is under immediate missile threat?
Answer: It means Europe is taking the question more seriously, but the public evidence still stops short of proving a confirmed, operational Iranian strike capability against London or Paris.
Question: Is this a proven fact or still a debate?
Answer: It is still a debate in public reporting. The most cautious position is that the concern is real, but the capability remains unconfirmed in official public assessment.
