Tens of thousands are gathering in Novi Sad for a rally marking the anniversary of a deadly train station awning collapse. The event reflects growing opposition to President Aleksandar Vučić amid ongoing protests for democratic reforms. Vučić has threatened arrests and downplayed the rally's significance, while tensions remain high after a year of protests. The initial focus on accountability for the tragedy has expanded to broader demands for change. Despite a bomb threat disrupting train services, large turnout is still anticipated.
