Hundreds of NATO troops sealed off the eastern Bosnian town of Pale today but failed to find Radovan Karadzic, the former Bosnian Serb wartime leader indicted for Europe's worst massacre since World War II.
Karadzic, who is 58, along with his military chief Ratko Mladic, has played cat-and-mouse with NATO-led troops since they were dispatched to Bosnia in 1996 to oversee the Dayton peace accords.
