BBC International correspondent Nawal Al Maghafi reports from Tehran, where authorities say they expect millions of people to take part in Ayatollah Ali Khamenei’s funeral commemorations.

Iran’s former supreme leader was killed more than four months ago in US and Israeli strikes at the start of the war.

Large crowds of black-clad mourners have already gathered at Tehran’s Great Mosalla Mosque, where his body lies in solemn state ahead of his burial in his hometown of Mashhad next Thursday.

The BBC’s senior international correspondent Nawal Al Maghafi reports from Tehran on the condition that none of her material be used on the BBC’s Persian service. These restrictions apply to all international media organizations operating in Iran.
