The UN-backed tribunal on Khmer Rouge genocidal crime has decided to adjourn hearings against two former Khmer Rouge leaders until early next year after lawyers for one of the defendants continued to boycott proceedings.

The Extraordinary Chambers in the Court of Cambodia said in its November 24 statement that the trail hearings will resume January 8 next year.

The tribunal in August sentenced the two former Khmer Rouge leaders - Noun Chea, 88, and Khieu Samphan, 83 - to life imprisonment for the charge of crimes against humanity after their first trial at the tribunal.

They have appealed against the verdicts.

They were among senior officials of the Khmer Rouge regime which was accused of killing an estimated 1.7 million Cambodians during their ruling from 1975 to 1979.

The UN-backed tribunal was established in 2006 to ask justice for the Khmer Rouge’s victims in Cambodia.

At its first trial in 2010, the tribunal gave life sentence to Kaing Guek Eav, known as Duch, who headed the notorious S-21 prison, with the charges of war crime and crimes against humanity.-VNA
