At least 71 child offenders were awaiting execution in Iran, Amnesty said in a report entitled, Iran: The last executioner of children.
It said that more child offenders had been executed in Iran than in any other country since 1990.
In its report, Amnesty listed the names of the 71 child offenders known to be facing the death penalty, but noted that the total number could be much higher as many death penalty cases in Iran are believed to go unreported.
Of the 24 child offenders recorded as having been executed since 1990, 11 were still under the age of 18 at the time of their execution while the others were either kept on death row until they had reached 18 or were convicted and sentenced after reaching that age, the group said.
