The United States and Iran have begun indirect talks in Geneva over their long-running nuclear dispute, with a senior Iranian official asserting that negotiations hinge on Washington avoiding unrealistic demands as the US masses a battle force in the region.
US envoy Steve Witkoff and US President Donald Trump's son-in-law Jared Kushner will take part in the negotiations, which are being mediated by Oman, a source briefed on the matter said, alongside Iranian Foreign Minister Abbas Araghchi.
Mr Trump said that he would be involved "indirectly" in the Geneva talks and that he believed Tehran wanted to make a deal.
"I don't think they want the consequences of not making a deal," Mr Trump told reporters aboard Air Force One last night.
"We could have had a deal instead of sending the B-2s in to knock out their nuclear potential. And we had to send the B-2s."
Tehran knows that a previous attempt to revive talks was under way in June last year when Washington's ally Israel launched a bombing campaign against Iran, and was then joined by US B-2 bombers that struck nuclear targets. Tehran has since said it has halted uranium enrichment activity.
A senior Iranian official said that US seriousness on lifting sanctions on Iran and avoiding unrealistic demands are key to ensuring effective talks in Geneva.
The official, who declined to be named, said Tehran was coming to the negotiating table with "genuine and constructive proposals".
The meeting is taking place at the residence of the Omani ambassador to the UN amid a heavy security presence. Some cars with Iranian diplomatic licence plates were visible outside.
The US military is preparing for the possibility of weeks of operations against Iran if Mr Trump orders an attack, two US officials said.
Iran itself began a military drill yesterday in the Strait of Hormuz, a vital international waterway and oil export route from Gulf Arab states, which have been appealing for diplomacy to end the dispute.

Watch: Trump warns Iran of consequences of not doing a deal
Tehran and Washington renewed negotiations on 6 February on their decades-long dispute.
Washington and its close ally Israel believe Iran aspires to build a nuclear weapon that could threaten Israel's existence.
Iran says its nuclear programme is purely peaceful, even though it has enriched uranium far beyond the purity needed for power generation, and close to what is required for a bomb.
Since the June strikes, Iran's Islamic rulers have been weakened by street protests, put down at a cost of thousands of lives, against a cost-of-living crisis driven in part by international sanctions that have strangled Iran's oil income.
The US has now placed what Mr Trump calls a massive naval armada in the region.
Iran has joined the nuclear Non-Proliferation Treaty, which guarantees countries the right to pursue civilian nuclear power in return for requiring them to forgo atomic weapons and cooperate with the UN nuclear watchdog, the International Atomic Energy Agency.
Israel, which has not signed the NPT, neither confirms nor denies having nuclear weaponry, under a decades-old ambiguity policy designed to deter surrounding enemies.
Scholars believe it does, having acquired the first bomb in 1966. Israeli journalists, circumscribed by military censorship, often refer cryptically to such capabilities or cite foreign media reporting on them.
Washington has sought to expand the scope of talks to non-nuclear issues such as Iran's missile stockpile.
Tehran says it is willing only to discuss curbs on its nuclear programme - in exchange for sanctions relief - and that it will not give up uranium enrichment completely or discuss its missile programme.
Yesterday, US Secretary of State Marco Rubio told a news conference in Budapest that it was hard to do a deal with Iran, but the US was willing to try.
Mr Araghchi met Rafael Grossi, head of the IAEA, in Geneva yesterday to discuss cooperation with the nuclear watchdog and technical aspects of the impending talks with the US.
This afternoon, Mr Witkoff and Mr Kushner will participate in three-way talks with Russia and Ukraine as Washington attempts to coax Ukraine and Russia into an agreement to end Moscow's four-year-old invasion of Ukraine, the source said.
