Iraq's ex-Deputy Prime Minister Tareq Aziz made his first public appearance in three years on the stand for Saddam Hussein on Wednesday, calling on the court to try current leaders for attacks on the state in the 1980s. Aziz, the highest profile witness for Saddam, was once the international public face of the toppled leader's government and one of his closest aides. He tried to turn the tables around in the trial that started in October by accusing one of the parties now in power, the Islamist Shia Dawa of new Prime Minister Nuri al-Maliki, of trying to kill him and Saddam in the 1980s.
