A US military judge sentenced Staff Sergeant Ivan Frederick to eight years in prison on Thursday for sexually and physically abusing detainees at the Abu Ghraib jail in Baghdad.Frederick's lawyer, Gary Myers, called the sentence excessive and said he would appeal. The other two soldiers so far tried for abuse at the jail were sentenced to eight months and one year in prison. Frederick, 38, had pleaded guilty to five charges of abusing detainees at Abu Ghraib in October and November last year, including making three prisoners masturbate. He also punched one prisoner so hard in the chest that he needed resuscitation.
