Aging Khmer Rouge leader Khieu Samphan, who was admitted to a Phnom Penh hospital Wednesday after suffering an apparent stroke, was recovering under armed guard and tight security, his wife said Friday.

He was given IV treatment and a brain scan, wife Sor Socheat said. "Now he's good."

Khieu Samphan is widely expected to face indictment by the Khmer Rouge tribunal for his role as nominal head of the regime. His apparent stroke occurred just one day after the detention of Ieng Sary and Ieng Thirith, two former leaders charged with crimes against humanity.

Family said following a collapse at his home last Tuesday that Khieu Samphan had fallen unconscious for a brief time. A government helicopter flew him from Pailin to Phnom Penh Wednesday.

Calmette Hospital Director Heng Tai Kry declined to comment on Khieu Samphan's current condition, saying only he was still under the hospital's care.
