The students, organised within the Borba ("Fight") movement, are calling for the election results to be annulled and new votes held. It will be the first day-long blockade since the December 17 parliamentary and local elections in which President Aleksandar Vucic's party said it secured a commanding victory, but opposition groups contested the results IMAGES AND SOUNDBITES
