EU warns Iran

The European Union warned on Monday that Iran’s move to enrich uranium to 20 percent would be a "considerable departure" from Tehran’s commitments under the 2015 nuclear deal.

EU spokesman Peter Stano said Brussels would wait until a briefing from the director of the UN’s IAEA nuclear watchdog later in the day before deciding what action to take.

Earlier, an Iranian government spokesman said the Shahid Alimohammadi enrichment complex in Fordow had begun the "process for producing" uranium enriched to 20 percent. That would be well above the 3.67 percent cap set in the deal, known as the JCPOA, or Joint Comprehensive Plan of Action.

"If this announcement is going to be implemented... it would constitute a considerable departure from Iran’s nuclear commitments under the JCPOA," Stano told reporters. This would have "serious nuclear non-proliferation implications".
