Boys as young as 15 are being recruited to fight in the Yemen Civil War, with promises of financial compensation to their families when they are martyred, according to a report from Amnesty International.

The statement was prompted after the families of three boys approached Amnesty International to report that their sons had been actively recruited and sent to fight for Houthi rebels.

Recruitment of at least two of the boys occurred while they were attending a Quranic school in the Yemeni capital of Sana’a, which is currently under Houthi control following an uprising as part of the Yemeni Civil War.

According to interviews conducted by Amnesty International, these types of schools have historically become breeding grounds for fighters. Instead of traditional school subjects, young boys are being taught sermons and lectures extolling the virtues of war against the invading Saudi-led coalition. With the chaos throughout Yemen as a result of the civil war, the various armed groups and militias are able to further exploit deteriorating conditions and indoctrinate children to become soldiers.
