The US on Wednesday announced new sanctions on dozens of individuals and entities tied to Iran’s nuclear and weapons programs, in support of the recent “snapback” sanctions by the UN on Tehran.

Secretary of State Marco Rubio said in a statement that 44 individuals and entities have been designated, including five people and one entity allegedly linked to Iran’s Organization of Defensive Innovation and Research (SPND), which he described as the successor to Iran’s pre-2004 nuclear weapons program.

The US also imposed additional export restrictions on 26 entities and three procurement-linked addresses.

“These actions highlight the importance of the September 27 re-imposition of sanctions and other restrictions on Iran pursuant to multiple UN Security Council resolutions,” Rubio said. “We will not hesitate to hold accountable anyone who supports Tehran’s proliferation activities.”

The measures come after France, Germany and the UK invoked a “snapback” mechanism under UN Security Council Resolution 2231, restoring sanctions that had been suspended since the 2015 nuclear deal.
