A United Nations committee focused on youth rights accused Israel Thursday of failing to stop the mistreatment of Palestinian children in military and police custody.

The group's report accuses Israeli forces of using Palestinian children as human shields, and alleges that detained children in some cases face torture, solitary confinement and threats of sexual assault.

Assembled by the U.N. Committee on the Rights of the Child, the 21-page document comes three months after a UNICEF paper criticized the "systematic and institutionalized" mistreatment of Palestinian children detained by the Israeli military.
