Iran says 'either all or nothing' on nuclear deal

The European signatories of Iran's nuclear deal with major powers should convince US President Donald Trump not to exit the accord as there is no "plan B" for the agreement, Iranian Foreign Minister Mohammad Javad Zarif Tweeted on Monday.

"It is either all or nothing. European leaders should encourage Trump not just to stay in the nuclear deal, but more important to begin implementing his part of the bargain in good faith," Zarif wrote on his Twitter account.
