A U.N. panel has concluded that the United States falls short of full compliance with an international anti-torture treaty.

The report by the U.N. Committee Against Torture cites police brutality, military interrogations, maximum security prisons, illegal migrants and solitary confinement among areas of concern.

Alessio Bruni of Italy, one of the panel's chief investigators, told reporters Friday in Geneva "there are numerous areas in which certain things should be changed for the United States to comply fully." The U.N. Convention Against Torture took effect in 1987, and the United States ratified it in 1994.

The U.N. committee's 10 independent experts are responsible for reviewing the records of all 156 U.N. member countries that have ratified the treaty against torture and all "cruel, inhuman or degrading treatment or punishment."
