The Associated Press has revealed new details about how the US military is running a secret prison at Guantanamo known as Camp 7. For the first time, the top commander of detention operations at Guantanamo — Rear Adm. Mark Buzby — has confirmed the existence of the mysterious prison. The military is reportedly holding fifteen so-called high-value detainees at Camp 7. But the military has refused to disclose where Camp 7 is located within the grounds of Guantanamo.
