UN sanctions on Iran officially reinstated: here’s what they target
All UN sanctions suspended under the 2015 deal with Iran snapped back into force at 8 pm Eastern Time on September 27, one month after European powers triggered the so-called "snapback" mechanism.
The sanctions, first imposed between 2006 and 2010 under six Security Council resolutions, were suspended in 2015 when Resolution 2231 endorsed the nuclear deal (JCPOA).
They covered arms embargoes, travel bans, financial restrictions, prohibitions on nuclear- and missile-related activity and the freezing of assets belonging to designated individuals and entities.
Resolution 2231 set an October 18, 2025 deadline after which many restrictions were due to expire unless a so-called "snapback" mechanism was triggered.
On August 28, 2025, Britain, France and Germany (the E3) triggered the mechanism citing Iran's failure to comply with its nuclear obligations, beginning a 30-day process that culminated in the sanctions' return.
