Iran is ramping up the recruitment of children as young as the age of 12 into military-linked roles tied to the Islamic Revolutionary Guard Corps (IRGC), according to new reports byIran’s Supreme Leader calling for Basij forces to remain central to the revolution.

Iranian officials have defended the policy by pointing to what they describe as strong demand among teenagers.

In a televised interview with Iranian state media, IRGC official Rahim Nadali said the minimum age was set at 12 because "teenagers and the youth repeatedly have come and said that they want to take part." 

"There is no excuse for a military recruitment drive that targets children to sign up, much less 12-year-olds," Human Rights Watch’s Bill Van Esveld said.

The reports come as the United Nations classifies the recruitment of children in armed conflict as a "grave violation," with international law prohibiting the enlistment of children under 15 and setting 18 as the standard for participation in hostilities.

Both organizations called on Iranian authorities to immediately halt the recruitment of minors and release those already serving. 

Iran's mission to the United Nations declined Fox News Digital's comment request.
