Iran says nuclear offer final chance

Ali Larijani told the BBC his offer in a letter on Sunday to the foreign ministers of Britain, France and Germany to pick up the talks was "our last word to the Europeans".

European foreign ministers have said they are studying the proposal but have yet to indicate if they will accept the offer, the first since Larijani became hardline President Mahmoud Ahmadinejad's pointman on the nuclear dossier.

However, Larijani's letter makes clear that Tehran has no intention of dropping its demand to enrich uranium as part of a full nuclear fuel cycle -- the key sticking point in the tortuous negotiating process with Europe.
