The foreign ministers of the UK, France, and Germany, collectively referred to as the E3, have issued a stark warning to Iran regarding the ongoing nuclear negotiations. They announced their readiness to reactivate severe sanctions if dialogue is not resumed by the end of August. This ultimatum follows a previous extension for discussions, which Iran has not yet acknowledged. The ministers conveyed in a letter to the UN that they would invoke a “snapback” mechanism to reinstate prior sanctions should Iran fail to limit its nuclear activities. Although Iran expressed willingness for further discussions under certain conditions, tensions have escalated, particularly after its recent breaches of previously agreed nuclear restrictions. The situation remains fluid as both sides grapple with the prospect of renewed sanctions and their implications.

The foreign ministers of Germany, France, and the UK have issued a decisive message to the UN, signaling their readiness to reinstate sanctions on Iran regarding its nuclear program if it does not resume negotiation efforts by the end of August. Known as the E3, these nations have expressed a willingness to trigger a "snapback" mechanism, indicating that previous sanctions could be activated without delay. They had originally offered Iran an extension until the end of August for negotiations, a proposal that has not received a response from Tehran.
In a recent letter addressed to the UN and its secretary-general, António Guterres, the foreign ministers—Jean-Noël Barrot (France), David Lammy (UK), and Johann Wadephul (Germany)—emphasized the necessity for Iran to remain compliant with limitations on its nuclear activities. The letter specifically stated that if Iran does not engage in diplomatic discussions by the end of August 2025, the E3 would be prepared to enact the snapback mechanism. This stance reiterates their commitment to deploying all diplomatic means available to prevent Iran from developing nuclear weapons, which Tehran has consistently denied.
In July, Iran's Deputy Foreign Minister Kazem Gharibabadi remarked that the reactivation of sanctions would be "completely illegal." The United Nations had previously lifted sanctions on Iran's nuclear program in 2015 following the signing of a nuclear deal involving the E3, the US, Russia, and China. However, after the US withdrew from the agreement in 2018, citing insufficient measures to hinder Iran's potential nuclear capabilities, all US sanctions were reapplied, prompting Iran to progressively violate the deal's restrictions.
The International Atomic Energy Agency (IAEA) reported in May that Iran had amassed over 400 kg of uranium enriched to 60% purity, a level that exceeds that used for civilian purposes and approaches weapons-grade material. As tensions escalated with Israel and the US, Iran's parliament opted to suspend cooperation with the IAEA in June, a decision that coincided with Israeli military actions against Iranian nuclear sites, leading to a brief military conflict.
In the wake of these developments, the E3 nations intensified their warnings to Iran, emphasizing the urgency of resuming compliance with the IAEA guidelines. The BBC has reached out to the UK Foreign Office for comment, while the Iranian diplomatic mission to the UN has yet to provide a response. The ever-evolving dynamics of this international negotiation continue to pique global interest as the deadline looms.
