Delegations from scores of countries, including heads of state, prime ministers, and senior officials from Russia, China, India, Pakistan, Iraq, Tajikistan, Turkey, and dozens of other nations, arrived in Tehran to pay their respects on Friday.

The funeral ceremonies will continue with similar events in the holy city of Qom on Tuesday, followed by processions at the shrines of Imam Ali (AS) in Najaf and Imam Hussein (AS) and Hazrat Abbas (AS) in Karbala on Wednesday.

The burial will take place on Thursday, July 9, at the holy shrine of Imam Reza (AS) in Mashhad, in accordance with the martyred Leader's will.
