United Nations Snapback Sanctions on Iran Reimposed -- Pre-JCPOA International Restrictions Restored (2025-09-27)

United Nations Security Council snapback sanctions on Iran take effect, reimposing all international sanctions and restrictions that had been lifted under the 2015 Joint Comprehensive Plan of Action. The snapback is activated under UN Security Council resolutions 1696, 1737, 1747, 1803, 1835, and 1929, with the U.S. leading the diplomatic effort to secure international cooperation. Key European allies -- the UK, France, and Germany -- support the snapback, marking a significant shift from their opposition to the U.S. withdrawal from the JCPOA in 2018.
