BAGHDAD: Iraq's former deputy premier Tareq Aziz received a life sentence Wednesday for his role in the 1980s killing of Shiite officials, a judicial spokesman said. Aziz, who was sentenced to death in October for other crimes, appeared in court with former interior minister Saadun Shaker, his co-defendant on charges of murdering the sons of Ayatollah Mohsen Al-Hakim, a key figure behind a 1960 Shiite political revival in Iraq. “The Iraqi High Criminal Court sentenced Tareq Aziz and Saadun Shaker to life imprisonment,” court spokesman Mohammed Abdel Sahab said, without specifying the number of people the pair was charged with killing. “This is a different case from the killing of members of the Dawa party,” for which Aziz was sentenced to death. Last October, Iraq's supreme criminal court found Aziz guilty of “deliberate murder and crimes against humanity,” and sentenced him to death. Aziz, a Christian and a close confidante of Saddam Hussein, has remained in prison since surrendering to American forces shortly after the invasion. Wednesday's verdict was the sixth prison sentence against Aziz. The Vatican, the European Union and several Western governments have called on Baghdad for clemency for Aziz, whose family says he is suffering from diabetes, high blood pressure and heart problems. President Jalal Talabani, who must approve the execution order before it is carried out, has said he would not sign it.
