Qatar’s ruler, Emir Sheikh Tamim bin Hamad al-Thani, has arrived in Iran, Iranian state media reported on Thursday, as the Gulf state tries to help end a row between Tehran and Washington over revival of the 2015 nuclear deal.
While Iranian state media portrayed the visit as proof of Iran's expansion of ties with regional countries, a source briefed on the visit told Reuters on Sunday that the emir's trip was aimed to bring the parties to the Iran nuclear pact to "a new middle ground".
