The former head of the Khmer Rouge's Tuol Sleng prison, or S-21, Kang Kek Ieu,

will stay in jail another three years after a military court prosecutor announced

May 6 he has been charged with crimes against humanity. Better known as Duch, he

had been held since May 10, 1999 on genocide charges. The only other former KR leader

in jail, Ta Mok, received a similar extension when his pre-trial detention period

expired in March. Negotiations for a UN-sponsored tribunal collapsed earlier this

year when the UN pulled out.
