Overview

• The E3 sent a letter to the U.N. Security Council launching the snapback mechanism, which would automatically reinstate measures lifted under the 2015 deal in late September unless action is taken to sustain relief.
• Restored measures would include an arms embargo, bans on enrichment and certain missile activities, asset freezes and travel bans, and authorities to inspect Iranian cargo for prohibited items.
• IAEA inspectors have returned to Iran in a limited role focused on Bushehr fuel work, while broader access to key sites and accounting for roughly 400 kilograms of 60% enriched uranium remain unresolved.
• Tehran warned it would halt cooperation with the IAEA and end direct talks with European capitals if snapback proceeds, saying future discussions would occur only in the Security Council framework.
• European diplomats signaled they could defer implementation for a limited period if Iran resumes full monitoring and engages seriously, as Russia and China push a rival draft to extend current arrangements to April 2026.
