Former Bosnian Serb commander Ratko Mladic, on trial for war crimes at The Hague, has been rushed from the courtroom to the hospital.
Officials for the International Criminal Tribunal for the former Yugoslavia said Mladic was taken into medical care Thursday as a precautionary measure, after he complained of not feeling well during the proceedings. He is expected to stay in the hospital Friday for a second day of tests.
Since his arrest in Serbia last year, after 16 years on the run, Mladic has complained his health is too poor to stand trial. But observers say the lapse was surprising because he had looked healthy in court earlier this week.
The 70-year-old Mladic has a history of strokes, pneumonia, and kidney stones.
Mladic is charged with 11 counts of war crimes and crimes against humanity, which carry a maximum penalty of life in prison. Charges against the former Bosnian Serb commander include the July 1995 Srebrenica massacre, in which some 8,000 men and boys were killed by troops under Mladic's command.
Former Yugoslav president Slobodan Milosevic also suffered ill health during his four-year trial at The Hague. He died of a heart attack in his cell in 2006, before the proceedings were complete.
