Senior diplomats from France, Britain and Germany taking part in talks on reviving the Iran nuclear deal on Friday expressed "disappointment and concern" at Tehran's proposed alterations to a text that had been agreed on in previous rounds.
"Major changes (have been) demanded (by Iran)," the officials said in a statement, adding that some were incompatible with the 2015 deal.
It is "unclear how these new gaps can be closed in a realistic timeframe on the basis of Iranian drafts," they said.
