Lawyer Milos Saljic said he was alerted by the International Tribunal for the Former Yugoslavia sitting at The Hague, Netherlands, that Mladic was taken to a hospital Monday, apparently because of pneumonia, Tanjug reported.
Tribunal officials did not provide more information, Saljic said.
Mladic was indicted by the tribunal on charges of genocide and war crimes committed in Bosnia-Herzegovina during the 1992-1995 conflict. Among other things, the former military commander of Serbs in Bosnia is accused in the massacre of up to 8,000 Muslim men and boys in July 1995 in Srebrenica and the prolonged siege of Sarajevo. He was arrested in northern Serbia May 26.
The last status conference Thursday was delayed for more than an hour because of Mladic's ill health, Tanjug reported.
