Iran says it\'s ready to negotiate a comprehensive and final deal on its nuclear energy program. The preliminary accord, which was reached on Sunday, meant to lay the foundations for a comprehensive agreement later this year. Zarif was speaking at Tehran\'s Mehrabad Airport upon arrival back home from Geneva. He said the Iranian nation showed that no one can talk to them through pressure. Zarif also said Tehran\'s right to uranium enrichment is enshrined in the nuclear deal. Based on the interim deal, Iran has agreed to limit the level of its enrichment activities for the next six months in exchange for the easing of sanctions. The foreign minister was given a heroic welcome by the people who\'d gathered at the airport several hours before his arrival. Show Less >>
