BELGRADE - Bosnian Serb war crimes suspect Ratko Mladic, awaiting trial in The Hague, has been admitted to hospital suffering from pneumonia, his lawyer said on Tuesday.

The former general has frequently complained of ill health, most recently last week, since his arrest and extradition from Serbia in May to face charges of genocide and war crimes during the 1992-95 Bosnia war.

His Belgrade lawyer, Milos Saljic, said the Yugoslav war crimes tribunal had informed him on Monday that Mladic had been transferred to hospital, "apparently because of pneumonia."

He said he had no further details. The press office at the tribunal was unable to confirm the information.
