United Nations nuclear inspectors arrived in Tehran on Sunday as part of a joint interim accord that would see Iran reduce its uranium enrichment in return for an easing of some Western sanctions, the Fars news agency reported.

Reza Najafi, Iran’s ambassador to the International Atomic Energy Agency, said the team will supervise the suspension of 20 percent-enriched uranium at the country’s Fordo and Natanz nuclear enrichment sites, according to Fars.
