Iran, US set for nuclear talks in Oman

Iran is approaching weekend talks with the United States over its nuclear programme warily, with little confidence in progress and deep suspicions over US intentions, Iranian officials told Reuters on Tuesday.

The talks were announced on Monday by US President Donald Trump, who has repeatedly threatened Washington's old foe Iran with military action if it does not agree to a deal since he returned to the White House in January.

Trump has said the talks on Saturday in Oman will be direct but Iranian Foreign Minister Abbas Araqchi repeated on Tuesday Tehran's position that they should be indirect, citing what he called US pressure and threats.

"Indirect negotiations can guarantee a genuine and effective dialogue," he told Iranian state news agency IRNA. Araqchi said the talks would be led by him and Trump's Middle East envoy Steve Witkoff, mediated by Oman's Foreign Minister Badr al-Busaidi.

A source briefed on US planning for the talks confirmed that Witkoff would lead the US delegation and that the discussions would be broad in the search for a nuclear deal and would not be technical in nature. "This is still coming together," the source told Reuters.

Tehran would want to see concrete gestures from the United States before any face-to-face talks between Iranian and US officials, Iranian and regional sources said. "The Iranians told us that direct talks are possible but there has to be a goodwill gesture. Lift some sanctions or unfreeze some money," a regional diplomat said.

Russia backs either direct or indirect talks between Iran and the US as a chance to de-escalate tensions, Kremlin spokesman Dmitry Peskov said on Tuesday, adding: "We know that certain contacts, direct and indirect, are planned in Oman."

Russia's lower house of parliament also ratified on Tuesday a 20-year strategic partnership with Iran, a sign of the deepening military ties between the two countries.

Efforts to settle a dispute over Iran's nuclear programme, which it says is purely for civilian use but which Western countries see as a precursor to an atomic bomb, have ebbed and flowed for more than 20 years without resolution.
