Jailed Khmer Rouge leader Ieng Sary was hospitalized Monday for treatment of a urinary tract problem, officials said Tuesday.

The former foreign minister of the regime was rushed to the hospital after urinating blood, and he remained in the hospital Tuesday.

Lawyer Ang Udom said his client should not be kept at a tribunal detention center ahead of his atrocity crimes trials.

“We complained about the detention because of his health, because the prison conditions are not good,” Ang Udom said.

Ieng Sary, 82, suffers from heart problems and has been to the hospital twice in 10 days, tribunal spokesman Reach Sambath said.

Ieng Sary was being kept at Calmette Hospital in Phnom Penh to be monitored, Reach Sambath said.

“The persons to decide whether he should stay in or out of jail are the five judges from the Khmer Rouge tribunal, following a hearing,” Reach Sambath said.
