Meanwhile, President Trump has said he is not happy with Iran after a third round of talks ended without a deal on the Iranian nuclear programme.

When asked how close he was to making a decision on military strikes on Iran, the US president said, I'd rather not tell you.

The foreign minister of Oman, which has been mediating in the talks, told CBS News that progress had been made, but more time was needed.

The Omani foreign minister, Badr al-Busaydi.

Our chief international correspondent, Lise Doucette, gave me her assessment of where things stand.

The third round of talks in Geneva between the Iranians and the Americans ended with the mediator, the Oman's foreign minister, Badr al-Busaydi, talking of significant progress.

And Iran's foreign minister, their top negotiator,

Abbas Arachi, said that these had been the most serious, the longest negotiations he'd ever had with the Americans.

So from those two sides, you had the real sense that there had been movement.

But there was silence from the two American envoys, which led many of us to ask, well, was progress really made?

And then suddenly...

The Omani foreign minister races to Washington for a meeting with the U.S.

Vice President J.D.

Vance.

And he's given a rare interview to CBS News to send a message.

And what is it?

We're making significant progress.

You repeated that again.

But he also gave more details, interestingly, about the kind of concessions he says Iran is willing to make for the very first time.

For example, that it will not accumulate uranium.
