Tareq Aziz takes stand for Saddam

Aziz, the first defence witness for Saddam at his trial for crimes against humanity, was once the international public face of the toppled leader's regime and one of his closest aides.

Aziz, whose family earlier this year said he was seriously ill, looked tired as he testified in the courtroom in Baghdad's heavily-fortified Green Zone where Saddam and his seven co- defendants are standing trial. Aziz is not among those accused.
