"All its bases are within our reach, we have access to them, and without hesitation we will target all of them in the host countries," Iran's Defence Minister Aziz Nasirzadeh said in response to US threats of military action if the talks fail.

US Secretary of State Marco Rubio said that Iran could have civilian nuclear power while importing enriched uranium but that it wanted to keep its enrichment programme as "a matter of national pride" and "as a deterrent".

A technical, expert-level nuclear meeting between Iran and the United States will be held on Saturday, coinciding with the third round of indirect talks mediated by Oman, Tehran announced Tuesday.

Iran has sent a response to a letter from US President Donald Trump that called for nuclear talks and warned of possible military action if it refuses, its foreign minister said Thursday.

The stakes were laid bare in a warning from Britain's foreign intelligence chief that Iran's nuclear ambitions posed a major global security threat, despite its weakened position after setbacks dealt to its Islamist allies Hamas and Hezbollah in the Gaza Strip and Lebanon.

The degree of anger and sympathy for the protesters, particularly among the American and European public, makes it near impossible to reach a nuclear deal, believes Vali Reza Nasr.

The US, meanwhile, says it is "disappointed" that there is "no progress made" after two days of indirect talks with Iran brokered by an EU envoy in Doha. President Joe Biden's administration has "made clear our readiness to quickly conclude and implement a deal on mutual return to full compliance".

Iran said Monday it will only return to Vienna in order to finalize an agreement to revive its landmark 2015 nuclear deal with world powers, with the last steps dependent on Washington.

Iran has been engaged in negotiations to revive the deal, known formally as the Joint Comprehensive Plan of Action (JCPOA), with France, Germany, Britain, Russia and China directly, and the United States indirectly.

Iran's supreme leader Ayatollah Ali Khamenei dismissed as "absurd" claims his country wants to acquire atomic weapons, in remarks on Thursday amid signs of a breakthrough in nuclear talks.

"The initiatives of the Iranian side and the negotiations that have taken place have put us on the right track," Hossein Amir-Abdollahian said.

Iran announced Thursday it has carried out a new space launch, in a move likely to irk Western powers amid tough talks on reviving a 2015 nuclear deal. Western governments worry that satellite launch systems incorporate technologies interchangeable with those used in ballistic missiles capable of delivering a nuclear warhead.

Atomic Energy Organization of Iran director Mohammad Eslami said the enrichment levels were related to the needs of the country.

The landmark 2015 nuclear accord was initially agreed between Iran and Britain, China, France, Germany, Russia and the United States. But it began unravelling in 2018 when then US president Donald Trump pulled out and reimposed sanctions, prompting Iran to start exceeding limits on its nuclear program the following year.

The seventh round of nuclear talks ended Friday after five days in Vienna, with delegations returning to their national capitals and expected to go back to Austria next week. Iran had paused the talks in June following the election of ultraconservative President Ebrahim Raisi.

Rafael Grossi, director general of the International Atomic Energy Agency (IAEA) said the talks he held in Tehran on Tuesday were "inconclusive" despite being "constructive".

The indirect negotiations in Vienna come amid mounting pressure on Iran, with Western nations warning that the clerical state's nuclear work is advancing to dangerous levels and Israel threatening to attack.
