Serbian President Aleksandar Vucic insisted Sunday that he would not cave in to the 140,000 protesters who rallied in the capital overnight demanding early elections, while vowing more arrests after clashes broke out.
Saturday's rally was one of the largest in more than half a year of demonstrations triggered by the roof collapse at a train station in the city of Novi Sad in November, killing 16 people -- a disaster widely blamed on entrenched corruption.
