MOSTAR – MOSTAR, Bosnia-Polls opened Sunday in the southern Bosnian city of Mostar for the first local election in over a decade in a city famed for its picturesque Ottoman architecture and its deep ethnic divisions.Split between Muslim Bosniaks and Catholic Croats, who fought fiercely for control over the city during the country’s 1992-95 war, Mostar has not held a local election since 2008, when Bosnia’s constitutional court declared its election rules to be discriminatory and ordered that they be changed.The dominant nationalist Bosniak and Croat political parties, the SDA and the HDZ respectively, have spent over a decade failing to agree about how to do that.
