Press reports addressed talks between Iran and Russia over supplying Tehran with S-400 air defense systems, after Russian President Vladimir Putin received Iranian Supreme National Security Council secretary Mohsen Rezaei, who conveyed a message from Iranian Supreme Leader Mojtaba Khamenei. In parallel, reports said iodine tablets were distributed to residents near Iranian nuclear facilities amid fears of a military confrontation, while Iran's Health Ministry denied that its officials had made statements on the matter.
