Nato follows-up on Karadzic information

Nato troops are blocking roads in eastern Bosnia and flying helicopters over an area where the most wanted war crimes suspect is presumed to be hiding.

A military spokesman says they are pursuing information concerning former Bosnian Serb leader Radovan Karadzic.

Dozens of armoured vehicles of SFOR have been seen driving along mountain paths close to the border with Montenegro and Serbia.

Karadzic and military commander, General Ratko Mladic, top the list of suspects wanted by the UN war crimes tribunal.

It has indicted them for genocide and other war crimes committed during the 1992-95 Bosnian war in which 250,000 were killed and creating 2 million refugees.

Since 1996, Karadzic and Mladic have been in hiding. Bosnian Serb authorities are blamed for refusing to surrender them to the tribunal.

Acting on tribunal warrants, Nato-led peacekeepers in Bosnia have arrested dozens of war crimes suspects since the end of the war.
