After years of on-and-off diplomacy, the agreement known as the JCPOA was finally signed by world powers four years ago, but then the United States withdrew last year.

One year on, Iranian leaders are threatening to produce more enriched uranium - which could be used to make nuclear weapons - unless other parties to the deal protect its economy from US sanctions.

Iran has given the European Union, China and Russia 60 days to comply, an ultimatum that has already been rejected by EU leaders.

However, they remain "committed" to keeping the nuclear deal alive and they're urging Iran not to abandon the agreement.

Can a way forward be found?
