Iran's Foreign Minister Zarif, architect of nuclear deal, resigns

>He gave no specific reasons for his decision.

>Zarif played the lead role in striking the deal under which Iran agreed to curbs on its nuclear programme in return for the lifting of international financial sanctions.

>He came under attack from anti-Western hardliners in Iran after the United States pulled out of the agreement last May and reimposed sanctions on Iran’s economy and its lifeblood oil industry that were lifted under the deal.

Looks like things are getting interesting in Iran.
