Of those, 169 were for drug-related offences, 153 for murder, 12 for security-related charges, and nine for rape.
Among those executed in April on security-related charges, seven were accused of ties to dissident political or religious groups, and one was accused of espionage for Israel.
Only two of the April executions were officially announced by the Iranian authorities.
Iran accounted for 64% of all known global executions in 2024, with at least 972 people executed, according to Amnesty International.
On Saturday, over 300 global figures—including UN experts, Nobel laureates, former ambassadors, judges, and human rights leaders— issued an urgent appeal for United Nations intervention to stop what they called a “campaign of politically motivated executions” in Iran.
