Iran's top nuclear negotiator said his European counterparts have proposed a guarantee that Iran won't be invaded if Tehran agrees to a permanent halt on uranium enrichment, the state-run Islamic Republic News Agency said on Sunday. Hasan Rowhani said the proposal is under discussion by Europeans and includes several important points such as "guarantees about Iran's integrity, independence, national sovereignty" and "non-aggression toward Iran," the agency reported. "If Europe enjoys a serious political will about Iran's nuclear fuel cycle, there will be the possibility of understanding," the agency quoted Rowhani as saying in a letter to outgoing Iranian president Mohammad Khatami.
