In the days leading up to the burial, millions of mourners have gathered across Iran and Iraq to pay their final respects. 

One of the most emotional moments of the farewell ceremonies was the sight of the small coffin of his 14-month-old granddaughter placed beside his own. 

After funeral processions in Tehran and Qom, followed by visits to the Iraqi holy cities of Najaf and Karbala, Ayatollah Ali Khamenei's body has arrived in Mashhad, where he will be buried amid an outpouring of grief and tributes from millions of supporters.
