Iran and the United States are set to begin a third round of indirect nuclear negotiations in Geneva, Switzerland, with Oman acting as mediator. Iranian Foreign Minister Abbas Araghchi arrived on Wednesday and met Omani Foreign Minister Badr Albusaidi ahead of Thursday’s session. Both sides have expressed a preference for diplomacy, though Washington has imposed sweeping new sanctions targeting more than 30 individuals, entities, and vessels linked to Iran’s oil sales and weapons programs. The talks come as the US expands its military presence in the Middle East, deploying additional aircraft carriers, destroyers, and fighter jets.

The negotiations follow earlier rounds in Oman and Geneva, where only a tentative understanding on broad principles was reached. US officials, including Vice President JD Vance and Secretary of State Marco Rubio, have accused Tehran of rebuilding its nuclear program and developing long-range missiles, while Iran insists on its right to peaceful nuclear technology and rejects US allegations. Iranian officials have warned that any US attack would trigger retaliation across the region.

Analysts note that major gaps remain over uranium enrichment and sanctions relief, leaving uncertainty about whether diplomacy can prevent further escalation between Washington and Tehran.
