Overview

  • Ayatollah Ali Khamenei labeled the U.S. proposal “100 percent against” Iran’s interests and reiterated that any deal must preserve domestic uranium enrichment.
  • Washington’s framework would cap Tehran’s enrichment at 3 percent for a limited period and transfer operations to a regional consortium monitored by the IAEA.
  • Five rounds of negotiations under Omani mediation have reached an impasse as Iran prepares to formally reject terms it views as infringing on its sovereignty.
  • The IAEA reports Iran added 133.8 kg of enriched uranium in three months—enough for multiple warheads if further refined.
  • Both Israel and the U.S. have warned they may resort to military strikes if diplomacy fails to limit Iran’s nuclear capabilities.
