Iran's representative to the International Atomic Energy Agency (IAEA) said on Sunday Iran had not yet delivered a letter to the agency outlining its nuclear fuel swap deal agreed last week with Brazil and Turkey.
"We have not handed in the letter," Ali Asghar Soltanieh told Reuters. Iran's IRNA news agency reported earlier on Sunday that Soltanieh had given the letter to the IAEA chief.
Iranian officials said the letter would be handed in on Monday.
