Human rights group Amnesty International has called on Iran to halt the execution of child offenders.
In a new report, it says Iran is the only country to have executed child offenders so far this year.
It lists the names of 71 other child offenders it says are known to be facing the death penalty.
The organisation defines a "child offender" as a person convicted of crimes they committed when they were under the age of 18.
"Only three other countries have executed child offenders in the past three years according to information received by Amnesty International," says Drewery Dyke of Amnesty International.
"In three years, Iran has executed more child offenders than all those other countries combined. It's now the case that as of June 2007, Iran is the only country to have executed child offenders, having executed two in 2007."
"It's a practice that is increasingly out of step with what Iranians themselves expect from their judicial system."
