Bosnian Serbs vote on 'national holiday,' in challenge to Sarajevo

Serbs in Bosnia headed to the polls on Sunday to decide whether to mark their "national holiday", in a referendum that has placed the country's fragile institutions under pressure. The vote is the brainchild of Milorad Dodik, nationalist leader of the Bosnian Serb-run entity Republika Srpska (RS). Some 1.2 million voters are entitled to cast a ballot on whether they want their "national holiday" to continue to be celebrated on January 9.
