Lawyers for for former Khmer Rouge leaders Ieng Sary and wife Thirith plan to file a petition against a tribunal decision to detain them ahead of atrocity crimes trials.
The courts said Wednesday they would not release the couple, arrested Monday and charged with crimes against humanity, for their roles as ministers under the regime.
The two could suffer increasing ill health if detained, the lawyers said.
"There is no benefit of detaining him," Ieng Sary attorney Ang Udom said.
Phat Pov Seang, lawyer for Ieng Thirith, said he was preparing the necessary documentation to appeal the detention.
