JNS.org – A new report from the International Atomy Energy Agency (IAEA), the United Nations-affiliated nuclear watchdog, found that Iran is continuing to fail to fully cooperate with an investigation into the country’s nuclear activity.

“Iran has not provided any explanations that enable the agency to clarify the outstanding practical measures,” the IAEA said in its report.

Last year, Iran agreed to provide the IAEA with information on three aspects of its nuclear program: alleged experiments with nuclear detonators, work on high-explosive charges used in nuclear blasts, and studies on the calculation of nuclear explosive yields.

“Iran insists on hiding this [nuclear program] from the international community at a time when the major powers are continuing to try and allow Iran to produce the core of such weapons, enriched uranium. These do not go together,” Israeli Prime Minister Benjamin Netanyahu said.

At the same time, Iran has taken the step of refraining from expanding tests on models of machines used to refine uranium, the IAEA said.

Iran and the P5+1 powers—U.S., U.K., France, Russia, China, and Germany—have a June 30 deadline to reach a final nuclear deal.
