Iran wants to make deal rather than face military action, Trump says

President Donald Trump has said Iran wants to make a deal rather than face US military action, despite Tehran's insistence that its missile and defence systems will "never" be up for negotiation.

"I can say this, they do want to make a deal," Trump told reporters at the White House on Friday when asked about a build-up of US military forces in the Gulf, without providing details.

He had warned Tehran on Wednesday that time was "running out" to negotiate a deal on its nuclear programme after a large US naval fleet had gathered near the country.

Iran's foreign minister said there were no talks planned with the US at present but that Tehran was open to negotiations based on "mutual respect" and trust.

Also on Friday, the Kremlin said the head of the Iran's Supreme National Security Council Ali Larijani had met Russian President Vladimir Putin.

They discussed "Middle Eastern and international issues" among other matters, state news agency Ria-Novosoti reported.

Iran insists its nuclear programme is entirely peaceful and has repeatedly denied accusations by the US and its allies that it is seeking to develop nuclear weapons.

Asked on Friday whether he had given Tehran a deadline by which to strike a deal, Trump said that "only they know for sure".

He told reporters: "Hopefully we'll make a deal. If we do make a deal, that's good. If we don't make a deal, we'll see what happens."

He said a large "Armada" was on its way to the region and declined to give a timeline for its withdrawal: "We'll see how it all works out. They have to float someplace, so they might as well float near Iran."

Iran's Foreign Minister Abbas Araghchi had said earlier that the country's missile defence systems would "never" be on the negotiating table, and repeated the government's position that its nuclear programme was peaceful.

At a press conference with his Turkish counterpart after talks in Istanbul to avert US action, he said preparations were needed for "fair and just negotiations".

He had said help was "on the way", before saying he had been told the execution of demonstrators had stopped.

On Thursday, he said he had told Iran that it had to do two things to avoid military action: "Number one, no nuclear. And number two, stop killing protesters."

The US-based Human Rights Activists News Agency (HRANA) said it had confirmed the killing of more than 6,300 people, including more than 5,900 protesters, since the unrest began at the end of December.

It said it was also investigating another 17,000 reported deaths received despite an internet shutdown after nearly three weeks.

Another group, the Norway-based Iran Human Rights (IHR), has warned the final toll could exceed 25,000.
