Rubio says no 'breakthrough' in US-Iran talks

US Secretary of State Marco Rubio suggested that there has been no progress regarding truce talks with Iran, accusing the country of making "unacceptable" demands.

"I don’t have any progress to report to you," Rubio told reporters at the Homestead Air Reserve Base in Florida. "You have a number of countries that continue to engage them with different ideas, but I wouldn’t say we’re on the verge of a breakthrough."

"The president would always prefer to solve this and every problem diplomatically. Sometimes that’s not possible, unfortunately," he added.

Rubio said if there was a chance for a deal, then Washington would "explore it".
