The US secretary of state, Marco Rubio, has described a 60-day sanctions waiver for Iran as “a temporary measure” while stressing that Washington expects Tehran to “live up to the commitments” made in the deal, Al Jazeera reports.

“If they don’t live up to those commitments, the president [Trump] has a lot of options at his disposal including — I’m not saying he’s going to do it, I’m saying including — reversing these sanctions,” Rubio has told reporters in Kuwait City.

“They made very straight-up commitments in Switzerland and the president has been very clear they need to keep those commitments,” he says.

“If they do, we’ll keep forward. If not, the president will have options at his disposal for what to do about it. Let’s hope they keep those commitments.”
