US President Donald Trump decided a year ago to pull out of the "worst deal ever" - the Iranian nuclear agreement that imposed limits on Tehran's nuclear activities.

Trump then reimposed sanctions on Iran and recently extended them to threaten those countries still party to the deal.

Iran has now reacted, warning the UK, France, Germany, China, and Russia that it will step up uranium production unless they meet their commitments within 60 days.

Russia is putting the blame on what it calls "lamentable" behaviour from the US, while EU leaders are warning Iran of possible consequences.

Can the deal be renegotiated and revived?
