Some 84 juvenile offenders in Iran currently await execution, however the true number may be much higher. Iran remains one of the only countries in the world which continues to execute children, all in violation of its commitments to international treaties, such as Under Article 37(a) of the UN Convention on the Rights of the Child, child executions are a clear violation of international law, which bans the practice. You can see further details regarding Iranian law, and past cases, in my previous post Child Executions in Iran Continue Despite Violation of International Law.
You can take action for Feda'i and other juvenile offenders, here. For further information on child executions in Iran please see Stop Child Executions; Minors on Death Row in Iran.
