Large crowds have gathered in Mashhad, and possibly also in Tehran, ahead of the burial of Iran's late supreme leader, Ayatollah Ali Khamenei. The burial is reportedly taking place at the Imam Reza shrine in Mashhad, although the timing was delayed due to the large crowds. The situation is uncertain, with reports of both a burial having taken place and ongoing preparations for the event, as well as new fighting erupting between the US and Iran.
