BERLIN (AP) — The top diplomats of Britain, France, and Germany threatened to reimpose sanctions on Iran as an end-of-the-month deadline nears for the country to resume negotiations with the West over its nuclear program and cooperation with the United Nations nuclear watchdog.

If Iran does not re-engage in talks with the US by the end of the month, sanctions will be reinstated, the E3 says.

France, Germany and the UK have told the UN they are prepared to trigger the reimposition of sanctions on Iran unless it resumes negotiations with the US over its nuclear programme.
