A French citizen imprisoned in Iran for more than 880 days has been freed and is back home, as is another French citizen held under house arrest in Tehran, French officials have said.

The pair’s liberation came as France and the rest of Europe are trying to jump-start talks with Iran over its rapidly advancing nuclear programme.
