UK PM Boris Johnson warns Iran that time is running out for salvaging nuclear deal

British Prime Minister Boris Johnson warned Iran on Tuesday that time was running out to salvage a 2015 nuclear accord with major powers.

In a call with Israeli Prime Minister Naftali Bennett, Johnson discussed the ongoing talks on the Iran nuclear deal in Vienna.

"The prime minister said the UK wants to see the negotiations in Vienna lead to full restoration of the JCPoA, but that we need Iran to engage in good faith," a Downing Street spokesman said.

"The diplomatic door is open, but time is running out to reach an agreement."

Iran said Monday it has detected a new "realism" on the part of Western countries, as further meetings in Vienna aimed at rescuing an accord on its nuclear programme got underway.

Negotiations to restore the 2015 accord between Tehran and world powers (United States, France, Britain, Russia, China, and Germany) began last year but stopped in June as Iran elected ultraconservative President Ebrahim Raisi.

The talks resumed in late November and the latest round was set to formally get underway on Monday after a three-day break for the end of year holidays.
