Bosnian television showed fresh footage Thursday of top war crimes fugitive Ratko Mladic apparently enjoying himself in family outings, including to a ski resort possibly last winter.

The images, which have been posted on the Internet video-sharing site YouTube, were first broadcast on Sarajevo-based FTV television Wednesday.

In some of the videos, Mladic appears slimmer and older than previously, but not significantly different, unlike his former political leader Radovan Karadzic, arrested in Belgrade last year disguised as an alternative healer.

The previously unseen images also show Mladic in various restaurants and apartments and at what appears to be military barracks in Serbia, almost always accompanied by his wife Bosa and son Darko.

The director of Serbia's office on cooperation with the ICTY, Dusan Ignjatovic, said the footage was probably old recordings which had already been handed over to The Hague-based tribunal.

"Right now, I cannot say exactly where the images are from," said Ignjatovic.

"However, we assume that these are recordings that were seized during searches here in Serbia, in different places, and these images were forwarded to the prosecutor's office in The Hague.

"Regarding the video estimated to have been filmed in 2008 or even this winter, at this moment we cannot say if it's true or not, but we believe that this is not a video of 2008," said Ignjatovic.

Mladic (67) has been on the run from the UN's International Criminal Tribunal for the former Yugoslavia (ICTY) since 1995, when he was indicted for genocide for allegedly orchestrating the Srebrenica massacre.

Like fellow genocide suspect Karadzic, now on trial before the ICTY, Mladic is widely thought to be hiding in Serbia, where some still consider him a hero of Bosnia's 1992-1995 war.

On Tuesday, an ex-bodyguard of Mladic gave a Belgrade court details about the wartime Bosnian Serb army chief's last known movements before he went underground, including shelter at Belgrade's Topcider military barracks.
