The funeral procession was held in Tehran on Thursday with several Iranian officials, including Interior Minister Abdolreza Rahmani Fazli and Police Chief Brigadier General Hossein Ashtari, in attendance, Press TV reported.
An unauthorized gathering by the Gonabadi Dervishes near a police station in Tehran led to violent clashes with the police, resulting in deaths of five security forces.
During the clashes, an attacker ploughed a bus through a group of policemen, killing three of them. Also two members of the Basij volunteer force lost their lives in separate car-ramming and stabbing attacks at the site.
In a statement on Wednesday, the Dervish cult strongly condemned the attacks, calling for the perpetrators of acts of violence to be brought to justice.
A funeral ceremony was also held for the pair on Wednesday.
As many as 30 security forces and several rioters were also injured in the attacks.
The protestors were demanding the release of some members of their community.
Speaking at the Thursday funeral, the Iranian interior minister said the deadly riots in northern Tehran were yet another plot designed by enemies to put pressure on Iran.
The Iranian police chief also addressed the crowd of mourners, vowing that law enforcement forces will give a firm response to any group seeking to disrupt public order and security.
More than 300 people, among them the drivers of the bus and the car as well as the main elements behind the incident, had been arrested.
