(USA Today) – A Kurdish boy who looks no older than 11 mans the entrance of a military base in northeastern Syria. His pants drag on the ground and his shirt hangs off his bony shoulders as he stands in an ill-fitting military uniform next to a Kalashnikov automatic rifle. Like many of the child soldiers in local Kurdish forces, he refuses to give his name or provide his age for fear of retribution. The State Department says it has raised concerns about the use of child soldiers, even as the U.S. aids these Kurdish fighters battling against Islamic State militants in Syria through airdrops of weapons and supplies provided by Iraqi authorities.
