More evidence has emerged that US troops in Iraq carried out extensive torture inside Iraqi jails. Newly released military documents show Marines carried out mock executions, used electric shocks and burned prisoners. The documents obtained through the Freedom of Information Act has revealed that at least13 Marines were court martialed for taking part in the abuse. Some were jailed. The names of the Marines were blacked out of the documents. None of there cases had been previously reported. In one case, three marines were convicted after they “ordered four juvenile Iraqi looters to kneel beside two shallow fighting holes and a pistol was discharged to conduct a mock execution”. The American Civil Liberties Union, which obtained the documents, has accused the Pentagon of withholding more information on torture in Iraq. Meanwhile the Pentagon has admitted that at least eight detainees have died in US custody in Afghanistan. The admission came following a critical report by Human Rights Watch that assailed the military’s “culture of impunity” on prisoner abuse.
