BRUSSELS, July 7 — The European Union today strongly urged Iran to stop actions that would undermine a landmark 2015 nuclear deal, saying it was in touch with other parties to the deal and may set up a joint commission to look into the issue.

"We are extremely concerned at Iran’s announcement that it has started uranium enrichment above the limit of 3.67 per cent,” spokeswoman Maja Kocijancic for EU foreign policy chief Federica Mogherini said in a statement.

"We strongly urge Iran to stop and reverse all activities inconsistent with its commitments ... We are in contact with the other JCPoA (Joint Comprehensive Plan of Action) participants regarding the next steps under the terms of the JCPoA, including a Joint Commission,” she said.
