State television said on Sunday that 30 members of the police and security forces were killed in Isfahan province and six others in Kermanshah in western Iran in the latest riots.
semiofficial Tasnim news agency reported that 109 security personnel had been killed in the protests across the country.
The Iranian Red Crescent Society, meanwhile, said a staff member died during an attack on one of its relief buildings in Gorgan, the capital of Golestan province.
State media also reported that a mosque was set on fire in Mashhad in eastern Iran on Saturday night.
The casualty figures were reported as Iranian authorities stepped up efforts to quell the country’s largest protests in years, which have seen thousands of people take to the streets in anger over the soaring cost of living and inflation.
The Ministry of Interior said the “riots” are gradually subsiding, while the attorney general has warned that those involved in the unrest could face the death penalty.
On Saturday, Ali Larijani, a top security official, accused some demonstrators of “killing people or burning some people, which is very similar to what ISIS does”, referring to the armed group ISIL.
Hassan Ahmadian, an academic at Tehran University, told Al Jazeera that the demonstrations that started two weeks ago turned violent on Thursday, calling it “one of the scariest days in Iran, including in Tehran”.
