Documents that allegedly link Saddam Hussein to crimes against humanity were the focus of the latest hearing in the trial of the former Iraqi president. The court heard a criminal expert’s report that said Saddam’s signatures were on documents connecting him with the killing of 148 Shi’ites after an attempt on his life in Dujail in 1982.Seven others are also on trial. Saddam and his half-brother and former intelligence chief, Barzan al-Tikriti, have refused to give the tribunal a sample of their handwriting. One of Saddam’s lawyers requested the court appoint other experts, saying those testifying were members of the Interior Ministry. The chief judge adjourned the trial until Wednesday to give the experts more time to study documents. Saddam could face the death penalty if convicted.
