Serbia ? Former Bosnian Serb leader Radovan Karadzic, accused architect of a campaign of ethnic mass murder and a war-crimes fugitive for more than a decade, was captured Monday by Serbian security forces, officials said.

Indicted on multiple charges of genocide and crimes against humanity, Karadzic for years eluded NATO forces and myriad investigators seeking to bring him to justice. He served as president of the self-declared Bosnian Serb Republic and came to symbolize the repression of an entire population of Bosnian Muslims.

Karadzic, 63, is accused, among other crimes, of overseeing the massacre of more than 7,000 Muslim men and boys in the besieged enclave of Srebrenica in 1995, the largest atrocity in post-World War II Europe.
