ANKARA (Reuters) - Iran's top authority Ayatollah Ali Khamenei said on Wednesday the Islamic Republic should immunize itself against international sanctions to strengthen its position in nuclear talks.Western powers have imposed penalties over Iran's disputed nuclear program which have slashed its oil exports, causing inflation to soar and the value of its currency to plummet."What would you do if they set a condition for lifting the sanctions that would compromise your (national) pride'," supreme leader Khamenei told a gathering, in comments published on official IRNA news agency."No official would accept it. Efforts must be made to immunize Iran against the sanctions," he said, without going into details on how that should be done.(Writing by Parisa Hafezi; Editing by Andrew Heavens)Join the conversation about this story Click here to read full news..
