Former Bosnian Serb military chief Ratko Mladic was hospitalized Thursday after complaining of feeling unwell at his genocide trial.
Mladic was checked by a nurse at the tribunal after feeling ill and then sent to hospital "as a precautionary measure," Yugoslav war crimes tribunal spokeswoman Nerma Jelacic said.
Mladic's trial on 11 charges of genocide, war crimes and crimes against humanity was adjourned for the day. It was scheduled to continue Friday either with witness testimony or an update on Mladic's health.
The first witnesses began testifying this week against the 70-year-old former general, who denies wrongdoing.
Mladic has previously complained of ill health and suffered two strokes during his 16 years as a fugitive but has looked healthy and alert in court this week.
His lawyer, Branko Lukic, did not immediately return calls seeking comment.
Since his arrest in Serbia last year, Mladic has undergone surgery in The Hague for a hernia and been treated for other ailments including a kidney stone and pneumonia.
Last year, judges rejected a proposal by prosecutors to hasten Mladic's trial, fearing his health was too fragile for a lengthy case that could drag on for years.
Prosecutors had suggested trying Mladic first for the 1995 Srebrenica massacre, for which he is accused of genocide in the killing of 8,000 Bosnian Muslims, before starting a separate trial on charges of masterminding other Serb atrocities throughout Bosnia's 1992-95 war that left 100,000 dead.
The tribunal has had bad experiences previously with defendants in ill health. Former Yugoslav President Slobodan Milosevic died of a heart attack in his cell in 2006, forcing a premature end to his genocide case. Milosevic's trial had dragged on for nearly four years, partly because of his health problems and partly due to his political grandstanding.
