[JURIST] Iran announced Sunday that it has submitted a letter to the UN stating that it would suspend uranium enrichment activities as part of a deal with the European Union to avoid UN Security Council sanctions. Iran's chief nuclear negotiator, Hassan Rohani, said the suspension will remain as long as talks with the EU over Iran's nuclear case continued. The agreement keeps in place the preliminary agreement reached a week ago in Paris, previously reported on JURIST's Paper Chase. Reuters has more.
