Saddam Hussein says he's on a hunger strike to protest the way the judge at his trial is treating the defendants.
Saddam today tells the judge he hasn't eaten for three days.
He didn't mention the hunger strike yesterday in court.
The former Iraqi leader began the session by shouting his support for Iraqi insurgents, declaring "Long live the mujahadeen."
Saddam's half-brother, who is one of seven co-defendants, has also had heated exchanges with the judge today.
The day's first prosecution witness was a former Iraqi intelligence official who testified from behind a curtain to keep his identity hidden.
