Bosnia's top Muslim leader has warned Serbia it risks sparking new conflicts in the Balkans by denying facts about the region's past and encouraging secessionist ideas beyond its borders. Bakir Izetbegovic, who represents Bosniak Muslims in the country's tripartite presidency, said Thursday that Serbia should finally embrace the truth about its murderous role in the Balkan wars in 1990s because "future cannot be built on lies." "Lies provoke violence, violence provokes conflicts," Izetbegovic said.
