In Washington, the Supreme Court heard arguments Tuesday in the case of two US citizens seeking to challenge their transfer to Iraqi military custody. Shawqi Ahmad Omar and Mohammad Munaf are being held at Camp Cropper near the Baghdad airport. An Iraqi court has convicted Munaf of kidnapping Romanian journalists in a case widely seen as a sham. Munaf’s lawyers say the judge had been prepared to dismiss the trial until two US military officials intervened and told him to order the death penalty. Munaf’s death sentence was recently overturned, but he could face more charges. Omar, meanwhile, was detained by US forces at his Baghdad home. He’s been accused of harboring insurgents.
