Talks between the US and Iran scheduled for Friday have been brought back from the brink of collapse after the US initially rejected Iran’s request to move them from Turkey to Oman without the presence of a group of Arab states.

Iran’s foreign minister said late on Wednesday that the talks would proceed in Oman after reports of a last-minute effort by Arab states to convince the White House not to walk away from negotiations.

“Nuclear talks with the United States are scheduled to be held in Muscat on about 10am Friday,” wrote the Iranian foreign minister, Abbas Araghchi. “I’m grateful to our Omani brothers for making all necessary arrangements.”

US officials have also indicated the talks in Oman will go forward. They will take place amid a massive buildup of US naval and airpower in the region and appear to be a last chance for Tehran to avert a US strike against the country’s leadership and nuclear programme.
