Acting Tehran Mayor Alireza Zakani said the ceremonies for the former supreme leader Ayatollah Ali Khamenei would be "the largest assembly in the history of the capital," according to Iranian media.
Khamenei, who for 37 years held ultimate authority in all key state matters, was killed at the age of 86 in missile strikes on his residential and working compound in central Tehran.
The attacks occurred on February 28, the first day of the war, when the United States and Israel launched strikes on Iran. Several members of his family, including his daughter and two grandchildren, were also reportedly killed.
Satellite images show significant destruction at the site, but it remains unclear whether bodies have been recovered and in what condition.
The funeral, originally planned for early March, was delayed due to the conflict. It is now scheduled to start on July 4. Iranian authorities only announced the ceremonies after a fragile ceasefire between Washington and Tehran came into effect.
