‘Red lines’ loom over 5th round of Iran-US nuclear talks

ROME, May 23 (AFP): Iranian and US negotiators met in Rome on Friday for a fifth round of nuclear talks, after a public disagreement over Tehran's uranium enrichment.
The talks, which began in April, are the highest-level contact between the foes since the United States quit a landmark 2015 nuclear accord during President Donald Trump's first term.
Since returning to office, Trump has revived his "maximum pressure" campaign on Iran, backing talks but warning of military action if diplomacy fails.
Iran wants a new deal that would ease sanctions which have battered its economy.
"The fifth round of indirect talks between Iran and the United States, led by Iranian Foreign Minister Abbas Araghchi and US special envoy to the Middle East Steve Witkoff, began in Rome, with the mediation of Oman," Iran's Tasnim news agency reported.
The fourth round of talks, in the Omani capital Muscat, ended with a public spat over enrichment.
Witkoff said Washington "could not authorise even one percent" enrichment -- a position Tehran called a red line, citing its rights under the nuclear Non-Proliferation Treaty.
Ahead of Friday's talks, Araghchi said "fundamental differences" remained with the United States, while adding that Tehran was open to its nuclear sites undergoing more inspections.
"We will not have an agreement at all" if the United States wants to prevent Iran from enriching uranium, he said.
Iran's official IRNA news agency reported that the talks in the Italian capital were scheduled to begin at 1:00 pm (1100 GMT).
They come ahead of a June meeting of the UN nuclear watchdog, the Vienna-based International Atomic Energy Agency (IAEA), and the October expiry of the 2015 accord.
The deal, known as the Joint Comprehensive Plan of Action, aimed to allay Western suspicions that Iran was seeking a nuclear weapons capability, an ambition that Tehran has consistently denied.
In return for curbs on its nuclear programme, Iran had received relief from international sanctions. But the accord was torpedoed in 2018 when Trump unilaterally withdrew the United States and reimposed sanctions.
A year later, Iran responded by ramping up its nuclear activities.
It is now enriching uranium to 60 percent -- far above the deal's 3.67 percent cap but below the 90 percent level needed for a nuclear warhead.
Analysts in Tehran said Iran was unlikely to back down.
"It's quite simple; if the US expects Iran to halt nuclear enrichment, then there can't be a deal," said Mohammad Marandi, a political scientist who was once an adviser on the nuclear issue.
The Atomic Energy Organization of Iran says the country's nuclear industry employs 17,000 people, similar to other countries where uranium is enriched for civilian use.
"The Netherlands, Belgium, South Korea, Brazil and Japan enrich (uranium) without possessing nuclear weapons," its spokesman Behrouz Kamalvandi said.
