More than 43 million people attended the funeral and farewell ceremonies of former Iranian Supreme Leader Ali Khamenei, breaking all previous records, according to Iranian authorities. The six-day mourning processions took place across Iran and Iraq, marking what officials described as the largest public gathering and funeral in human history.

Fars News Agency reported that the ceremonies were held in Tehran, Qom, Najaf, Karbala, and Mashhad. The Iraqi Prime Minister’s Office confirmed that nearly ten million people joined the events in Najaf and Karbala alone. Khamenei was killed along with his family in a U.S. terrorist attack in February, and the formal farewell began last Friday, attended by political leaders from over 45 countries and scholars and representatives from more than 90 nations.

Independent sources verified the attendance figures using travel data and mobile signal analysis, according to Press TV.
