Two prisoners were executed at Sanandaj Central Prison on a charge of "intentional murder," according to Hengaw Organization for Human Rights.
Iran recorded a significant increase in death sentences and executions of demonstrators.
Widespread protests spread in Iran after the death of Mahsa Aymani, who was arrested by the morality police in Tehran in September 2022.
On Friday, the Iranian Human Rights Organization said that authorities issued 18 death sentences, including six women, and will be carried out in the coming days.
It announced that prison authorities informed the 18 prisoners, including two women in the Dastgerd prison in Isfahan and four others in the Dolat Abad women's prison.
Among the inmates was Samira Abbasi, a child bride who was sentenced to death for the premeditated murder of her husband.
Iran International reported that Iran is among the countries that have the highest number of executions in the world every year.
Meanwhile, Human Rights Watch (HRW) warned Friday of the "dramatic escalation" of executions in Iran in recent weeks, saying it is a "serious violation of the right to life and should bring international condemnation."
The Beirut branch of the human rights organization announced that Iran witnessed during the past two weeks at least 60 executions, including an Iranian-Swedish national, on alleged terror-related charges.
Many of them were executed after unfair trials or for charges such as drug offenses and two executions for "blasphemy," that under international law should never result in the death penalty.
The director of the Iran Human Rights Organization, Mahmood Amiry-Moghaddam, warned of the unprecedented wave of executions in Iran, especially among women.
Amiry-Moghaddam called on the international community to "stop the killing machine," warning that hundreds of people will be victims of this regime in the coming months.
An informed source told the organization that two men and two women were informed of the date of their execution in Dastgerd Prison. They were sentenced to retribution on charges of premeditated murder.
He added that 14 other prisoners were sentenced to death on drug-related charges.
