The expected announcement of a potential US-Iran agreement has been delayed partly because of the difficulty of communicating with Iran’s Supreme Leader Mojtaba Khamenei, who is believed to be living under tight security in a secret bunker.For all the latest headlines follow our Google News channel online or via the app.According to CBS news, US officials familiar with the intelligence say Khamenei is “effectively holed up” in an undisclosed location, with little access to the outside world. They say he can only be reached through a complex network of intermediaries and couriers, slowing Iran’s response to US proposals.The network also reported that Iranian officials involved in negotiations with the Trump administration are struggling to communicate within their own government system, which has slowed progress in the talks.A senior US administration official told CBS that Khamenei has agreed to the broad outlines of the current draft agreement, while President Donald Trump said in a Truth Social post that he expects a final decision in the coming days.Mojtaba Khamenei was injured during US and Israeli strikes on Iran on February 28, which killed his father, slain Supreme Leader Ali Khamenei. The report said Mojtaba Khamenei has not been seen or heard from publicly since before the start of the war.
