Organizers of Cambodia's Khmer Rouge tribunal say they have failed to agree on the rules that will govern the U.N.-backed proceedings.
Cambodian and international judicial officials issued a statement in Phnom Penh Saturday saying they could not agree on several issues, including how to integrate Cambodian law with international standards.
The officials have been discussing more than 100 rules for the trials over the past week.
They said no one wishes to delay the long-awaited trials and that they are strongly determined to establish a firm foundation for the court.
The tribunal will seek justice for crimes committed by the Khmer Rouge between 1975 and 1979.
The ultra-Maoist group killed nearly two million people through execution, overwork, disease and malnutrition in their quest to establish a perfect peasant society.
As many as 10 former Khmer Rouge leaders could be tried.
