It is difficult to estimate the number of underage Afghans fighting in Syria, but former fighters have described the number of Afghan combatants as being in the thousands.Iranian authorities deny they are sending Afghans to fight in Syria in any official capacity. The Afghan foreign ministry promised last year to probe reports of Iran recruiting Afghan refugees, but it has not said anything since. However, former fighters have told the media and human rights organizations that IRGC trained and deployed them. Stories on the social media accounts of some of these fighters speak of battlefield visits they received from Gen. Qasem Soleimani, commander of the IRGC’s Quds Force, which is responsible for international military operations. Iranian officials are also frequently seen attending funerals of Afghan fighters killed in Syria.
