Rubio also stated that there was a "growing split" in Iran between the more militant extremists who continue to attack the US and other countries and those who are concerned with Iran's economy.
The United States is still open to a diplomatic solution with Iran, US Secretary of State Marco Rubio told reporters on Sunday night.
"It has to be real," he explained. "It has to be a deal that they're willing to live by.
"Look, Iran, a week ago, was supposed to put out a statement saying that the Straits of Hormuz would be open, that they would no longer attack shipping. And instead of doing that, they attacked three ships. I think that was last Friday or Saturday. So, I mean, their behavior has to change in order for ours to change."
Rubio also stated that there was a "growing split" in Iran between the more militant extremists who continue to attack the US and other countries and those who are concerned with Iran's economy.
"If the guys that want to do something productive for Iran win and take control of that system or take control of the negotiations, that'll be a very positive development," he said.
