Islamic State has claimed responsibility for Wednesday’s attack on a crowd in southern Iran marking the anniversary of the death of the senior Revolutionary Guards commander Qassem Suleimani.

At least 84 people died when two blasts ripped through the crowd near Suleimani’s tomb in the city of Kerman, four years after he was killed by a US drone strike in Baghdad. Suleimani had been a staunch enemy of IS, which resents the damage he did to its cause in Iraq and Syria.
