London said today the European Union will in one week deliver "full and detailed proposals" to Iran aimed at ending the crisis over its nuclear program. Iran has demanded the proposals by today, or else it will resume uranium enrichment activities. But a British Foreign Office statement urged Tehran not to take any "unnecessary and damaging step" by restarting uranium conversion. The statement warned that such a move could jeopardize talks between Iran and EU negotiators - Britain, France and Germany. Earlier, Iranian negotiator Ali Agha Mohammadi told AFP that Tehran had given Brussels a deadline of 1430 Prague time today to submit proposals. He added that Iran will risk being hauled before the UN Security Council, if the EU fails to recognize its right to uranium conversion activities. The EU trio is to offer incentives to be provided in return for Iran guaranteeing its nuclear program is peaceful.
