Tillerson woos Gulf allies in push to undercut Iran

Top US diplomat Rex Tillerson pursued efforts to curb Tehran's influence in talks with his country's Gulf allies Sunday, demanding that Iran pare down its involvement in Iraq as the fight against the Islamic State group draws to a close.Tillerson's visit to the Gulf, his third as secretary of state, also aims at persuading Qatar and a rival Saudi led-alliance to open the door to dialogue -- a goal he said had come to a deadlock Sunday.
