Iran has commuted death sentences against six juvenile offenders following UN criticism it was executing people who had committed crimes as children at “an unprecedented rate,” a report said Thursday.

Prosecutors asked the judiciary to reconsider 10 cases, the Shahrvand newspaper quoted Tehran chief prosecutor Abbas Jafari Dolatabadi as saying.

“Six requests were accepted and their death sentences overturned,” he said.

International conventions outlaw the death penalty for offenses committed by minors but Iranian law allows executions of those convicted of such offenses once they reach 18.

However, it also allows for death sentences to be commuted to compensation to victims’ families if it is determined that the juvenile offenders did not understand the full gravity of their actions.

Shahrvand did not specify what the judiciary decided in the other four cases referred to it.

Last week, UN human rights experts appealed to Iran to cancel the looming execution of Hamid Ahmadi who was 17 when he was sentenced to death in 2009 for the fatal stabbing of a young man during a fight.

They said that last month they intervened to halt the execution of another juvenile offender, and that they had learnt too late that two others were hanged on January 15 and 18.
