Serbia voted on Sunday in a knife-edge presidential election that could decide whether it turns its back on the West in response to the imminent loss of the breakaway province of Kosovo. The race between pro-Western President Boris Tadic and nationalist challenger Tomislav Nikolic is too close to call. REUTERS/Damir Sagolj (SERBIA)
