U.N. nuclear agency reports with "regret" no progress in monitoring Iran's growing enrichment program

United Nations — "No progress." That's the United Nations' nuclear watchdog agency's latest assessment of international efforts to monitor and verify Iran's nuclear program.

The global body's work, stemming from the now-defunct 2015 Iran nuclear deal (JCPOA), related to "verification and monitoring has been seriously affected by Iran's decision to stop implementing its nuclear-related commitments under the JCPOA" one of the two reports dated September 4 said.

The still-unpublished quarterly reports, obtained by CBS News, on Iran's nuclear advancement said the "situation was exacerbated by Iran's subsequent decision to remove all of the Agency's JCPOA-related surveillance and monitoring equipment."
