Iran's top negotiator and its foreign minister were in Doha for talks with Qatar's prime minister on a potential deal with the U.S. to end the three-month-old war, an official briefed on the visit said on Monday, after Washington and Tehran played down hopes for an imminent breakthrough.
U.S. Secretary of State Marco Rubio told reporters in New Delhi earlier that the U.S. would give diplomacy every chance to succeed before considering whether to deal with Iran in "another way".
