Iran says it will hold a three-day state funeral for late supreme leader Ayatollah Ali Khamenei, who was assassinated in US-Israeli strikes on the first day of the Middle East war, at a date to be announced, AFP reports.

A state funeral initially planned for March 4 was postponed due to the war.

“A three-day public funeral is planned,” Tehran Deputy Mayor Mohammad Amin Tavakolizadeh is quoted as saying by state television.

He has not specified when the funeral will take place, but says it could be in early Muharram.

Tavakolizadeh adds that funeral events will take place in Tehran, as well as in the holy cities of Qom and Mashhad, where Khamenei will be buried.

“In Tehran, the ceremony will last at least 24 hours,” Tavakolizadeh states, adding that up to 20 million people are expected to attend.
