US President Donald Trump said on Friday that he is "not happy" with the ongoing negotiations with Iran, asserting that Tehran must say it will not develop nuclear weapons.While addressing a gathering in Texas, Trump claimed that his administration has to "make a big decision," adding that any deal with Tehran must be "meaningful."

"Now we have a big decision to make. You know that. Not easy. We have a very big decision to make. We have a country that has, for 47 years, been blowing people's legs off, arms off, the face. They've been knocking out ships, killing people — lots of people. Well, not only Americans, lots of people. It's been terrible. 32,000 people killed over the last two, three months — protesters," Trump said."32,000. That's a number of people. They want to make a deal, but you’ve got to make a deal that's meaningful.

I spoke with Ted Cruz, John, all of them on the way here. I said you’ve got to make a deal that's meaningful. We hit them real hard, as you know, with those beautiful B-2 bombers recently, knocked out their nuclear capability. But I'd rather do it the peaceful way. But they're very difficult people. I want to tell you that.

They're very dangerous people, very difficult people," he added.This comes after the third round of negotiations between Iran and the United States was held in Geneva on Thursday.

The latest round of talks comes amid ongoing diplomatic efforts to ease tensions between Tehran and Washington and against the backdrop of a significant US military build-up in the Middle East, as several countries advised their citizens to leave Iran amid concerns over potential US strikes.Earlier in the day, Trump said he is "not exactly happy" with Iran's handling of negotiations over its nuclear programme, stressing that the country cannot possess nuclear weapons."We haven't made a final decision (on Iran). We're not exactly happy with the way they're negotiating. They cannot have nuclear weapons. And we're not thrilled with the way they're negotiating. So we'll see how it all works," Trump said."I am not happy with the fact that they are not willing to give us what we have to have. I'm not thrilled with that. We'll see what happens. We'll have some additional talks today. But, no, I'm not happy with the way they're going," he added.
