Islamic State used two bombers to carry out the attack in the southern city of Kerman.
The two men have been named as Omar al-Muwahid and Sayfullah al-Mujahid and used remote controls to detonate the bombs that had been placed in bags.
The blasts took place about 15 minutes apart near the Martyrs Cemetery near the Saheb-al Zaman Mosque.
Supporters had gathered there to mark Qasem Soleimani's death, who had been assassinated in 2020 by an American drone strike.
