Iran will not give its final answer at a meeting this week to a package of proposals backed by six world powers that aims to end a nuclear standoff with the West, an Iranian nuclear official said on Sunday. Iranian chief nuclear negotiator Ali Larijani meets European Union foreign policy chief Javier Solana on Tuesday, when the EU has said it wants a "substantial response" to the offer. Iran previously said it would not give a final response on Tuesday, but by repeating the comment a day before the meeting, the official undermined any prospects of a breakthrough. |
