BELGRADE, Serbia — Ratko Mladic’s son says the war-crimes suspect suffered two strokes while on the run, has a partially paralyzed right hand and can barely speak.

Darko Mladic told reporters Friday after visiting his father in jail that “We will ask that he be transferred to a hospital.”

Prosecutors say the defense is simply trying to delay Mladic’s extradition and he is healthy enough to stand trial.

A police photo of Mladic showed him looking hollow-cheeked and shrunken after a decade and a half on the run, a far cry from the beefy commander accused of personally orchestrating some of the worst horrors of the Balkan wars.

Mladic was due back in court for a second hearing on his extradition to to the U.N. tribunal in the Netherlands on war crimes charges.
