Spokesperson for Iranian Ministry of Foreign Affairs: 'Our position is clear. The insecurity that America has imposed must be resolved by stopping all aggression, economic sanctions, and naval blockade. Our position was clear and we included our views in the memorandum of understanding. The problem was America, which violated its obligations 26 days after the understanding. The ball has been in America's court for a long time, they themselves initiated the aggression and they themselves violated their obligations in the memorandum of understanding' - reports
