Iranian overtures towards Gulf Arab countries after Tehran signed a landmark nuclear deal with world powers are to keep "brothers" updated, parliament speaker Ali Larijani said Thursday. Visits by top officials to the monarchies "are **rmal, because Iran considers the countries in the region to be friends", Larijani told reporters in Muscat after meeting Sultan Qaboos. Iran is locked in a decades-long rivalry with Saudi Arabia, while some other mainly Sunni Gulf countries are wary of the ambitions of their neighbour across the water.
