🇮🇷🇷🇺⚡️ — Iran and Russia are negotiating the delivery of advanced S-400 air defense systems, according to The Telegraph. Iranian security chief Mohsen Rezaei delivered a personal letter from Supreme Leader Mojtaba Khamenei to Vladimir Putin on Thursday, with Tehran optimistic about securing the systems it has sought for years. Iran hopes to rebuild its air defenses following this year's U.S. and Israeli strikes. Moscow may hesitate to deliver S-400 systems because of its own air defense requirements amid Ukrainian drone and missile attacks, as well as concerns about relations with Israel and other regional countries.
