Exclusive: U.S., others agreed 'secret' exemptions for Iran after nuclear deal

The United States and its negotiating partners agreed "in secret" to allow Iran to evade some restrictions in last year's landmark nuclear agreement in order to meet the deadline for it to start getting relief from economic sanctions, according to a report reviewed by Reuters.

The report is to be published on Thursday by the Washington-based Institute for Science and International Security, said the think tank’s president David Albright, a former U.N. weapons inspector and co-author of the report. It is based on information provided by several officials of governments involved in the negotiations, who Albright declined to identify.
