In Cambodia, the Khmer Rouge's infamous prison chief known as Duch, has been found. The former torturer had gone into hiding after he agreed to go on trial and testify against other Khmer Rouge leaders.

For years, while he was hiding, it was thought Duch was dead. Then some journalists found him last month.

Human rights groups were worried former Khmer Rouge leaders might go after Duch and urged the government to promise to protect him until his trial. But the government was slow to react, and Duch went back into hiding a few days after giving the interviews.

On Wednesday, Cambodian Prime Minister Hun Sen signed an order calling for Duch to be found and promising protection.

Duch, whose real name is Kaing Khek Iev, was head of a prison which tortured and killed more than 14,000 people.

The Khmer Rouge is blamed for the deaths of 1.7 million people in Cambodia before they were ousted in 1979.

Only one Khmer Rouge leader faces trial for the killings. The other leaders have negotiated deals with the government.
