Former Khmer Rouge leaders testify

Cambodians have waited decades for this moment.
On Monday a U.N. backed court in Phnom Penh began hearing testimony from three of the Khmer Rouge's former leaders.
They are charged with crimes against humanity, war crimes and genocide during Pol Pot's rule that resulted in the death of millions.
The trial has been delayed many times, frustrating survivors looking for answers.

"We know that these top Khmer Rouge leaders like Khieu Samphan said that what they did was for the good of the nation, but why did that cause the killing of millions of people and what were their responsibilities? If they deny that they killed the people, what will they tell the court or what evidence do they have to show the court? I want to know why many of our people were killed then."
Almost every Cambodian has lost a family member in the "Killing Fields" where people who were murdered, tortured or starved to death were buried.
Many here hope for justice, but worry the trial will ultimately fail.
