The organization describes the increase as "alarming" when it comes to the use of the death penalty.
"It is unprecedented in the last 35 years. In the entire time that Iran Human Rights has existed, we have never seen such numbers," says IHR founder Mahmood Amiry-Moghaddam.
Over 700 of the at least 1,500 executed have been sentenced to death for drug-related crimes.
In 2024, at least 975 people were executed in Iran, according to IHR and the France-based group ECPM.
Iranian authorities use the death penalty as an instrument to create fear, says Amiry-Moghaddam.
