33 years after Iraq chemical attack, survivors still seeking justice

Hawker Saber is one of the survivors of the chemical attack Saddam Hussein ordered on the Kurdish town of Halabja 33 years ago but he needs a respirator to stay alive. Saber, who is hooked to the machine for more than 20 hours a day, was just three at the time but he still has terrible memories of March 16, 1988.
