Vienna, Austria ? Iran is ready to consider complying – at least temporarily – with a U.N. Security Council demand that it freeze uranium enrichment, which can be used in developing atomic weapons, diplomats said Sunday.

Such a concession would be a major departure by Tehran as it faces possible U.N. sanctions for its nuclear defiance and would be a huge step toward defusing a confrontation over the program it says is only aimed at generating electricity.

The compromise was mentioned by senior Iranian nuclear negotiator Ali Larijani during two-day talks that ended Sunday with European Union foreign policy chief Javier Solana, the diplomats said.

One of them said Larijani floated the possibility of Iran stopping its enrichment activities “voluntarily, for one or two months, if presented … in such a way that it does it without pressure.” The diplomats did not say when such a move might occur.
