The first witness to appear in person at the trial of Saddam Hussein has given graphic testimony about the 1982 killing of more than 140 people in a mainly Shi'ite town.
Ahmed Mohammed Hassem said he knew several people killed in Dujail after an assassination attempt on Saddam there. His testimony was interrupted by exchanges with one of Saddam's seven co-defendants -- his half-brother Barzan Ibrahim.
Before the judge adjourned proceedings, Saddam told the court he is not afraid of execution. He earlier yelled out "long live Iraq, long live the Arab state." Court officials say the trial will resume Tuesday.
Also on Monday, one of Saddam's lawyers, former U.S. Attorney General Ramsey Clark, demanded better security for defense lawyers, two of whom have been killed. On Sunday, Iraqi authorities said they had foiled an insurgent plot to bomb the trial during on Monday's proceedings.
