Britain, France and Germany have reimposed sweeping United Nations sanctions on Iran, warning Tehran against escalation while pledging that diplomacy remains possible.
In a joint statement issued early Sunday, the three governments — collectively known as the E3 — said they had “no choice” but to trigger the so-called snapback procedure after years of what they described as Iranian breaches of its nuclear commitments.
“We urge Iran to refrain from any escalatory action,” the E3 foreign ministers declared. “The reimposition of UN sanctions is not the end of diplomacy.”
Sanctions return a decade after lifting
The UN’s comprehensive economic and military sanctions were officially reinstated at 00:00 GMT on Saturday. The measures, which had been lifted in 2015 under the landmark Joint Comprehensive Plan of Action (JCPOA), target Iran’s financial sector, arms imports, and trade in nuclear-related materials.
The E3 said they acted “as a last resort” after years of failed negotiations. They cited Iran’s decision to expand uranium enrichment, limit inspections by the International Atomic Energy Agency (IAEA), and refuse to meet European demands for confidence-building steps.
“Iran has not authorised IAEA inspectors to regain access to nuclear sites, nor has it produced and transmitted to the IAEA a report accounting for its stockpile of high-enriched uranium,” the statement said.
Iran pushes back
Iran’s President Masoud Pezeshkian condemned the move, calling the reimposition of sanctions “unfair, unjust, and illegal.” He insisted that Iran has “no intention of developing nuclear weapons,” a claim long disputed by Western powers and Israel.
Speaking in Tehran on Friday, Pezeshkian warned that while Iran had resumed limited cooperation with the IAEA, its willingness to maintain inspections could be jeopardised by renewed sanctions. “Why would we put ourselves in such a trap and have a noose around our neck each month?” he said, rejecting a U.S. proposal that Iran surrender its enriched uranium stockpile in exchange for temporary relief.
Tehran also announced it was recalling its ambassadors from Britain, France and Germany “for consultations.”
The JCPOA’s troubled history
The JCPOA, reached in 2015 between Iran and six world powers, placed strict limits on Iran’s nuclear activities in exchange for sanctions relief. However, the agreement began unraveling in 2018 when then-U.S. President Donald Trump unilaterally withdrew, calling it a “bad deal.”
Iran subsequently ramped up enrichment beyond permitted levels and restricted international oversight. Tensions escalated further after Israeli and U.S. strikes on several Iranian nuclear and military facilities in June, prompting Tehran to suspend IAEA access.
Although inspections resumed in recent weeks, Western diplomats say Iran has still not provided full transparency. “Iran has repeatedly breached these commitments,” the E3 said in their statement. “Given this, the E3 had no choice but to trigger the snapback procedure.”
Diplomacy not dead
Despite the sanctions, European leaders stressed that channels remain open. “This is not the end of diplomacy,” the E3 underlined, noting that discussions with Iran on the sidelines of the UN General Assembly last week had failed but further talks are possible.
Iran has hinted it might reconsider its posture if it receives security guarantees, particularly assurances that its nuclear sites will not be attacked by Israel. President Pezeshkian has also backtracked on earlier threats to withdraw from the Non-Proliferation Treaty, signaling Tehran still sees value in remaining within international frameworks.
Outlook
The sanctions snapback is likely to further strain relations between Iran and the West at a moment of high regional tension. Analysts warn the measures could deepen Iran’s economic crisis, raise oil market volatility, and heighten the risk of confrontation in the Gulf.
For now, both sides appear locked in a standoff — Europe insisting sanctions are unavoidable until Iran complies, and Tehran rejecting what it sees as coercive ultimatums while demanding security guarantees.
Whether diplomacy can still rescue the JCPOA framework, or whether the confrontation will spiral, remains uncertain.
