Tens of thousands of people protest in Belgrade, Serbia, calling for early elections and urging change in the government led by President Aleksandar Vucic. During the demonstration, police clash with protesters. Officers use crowd-control measures, firing teargas and stun grenades. Despite the confrontation, the rally continues and proceeds as planned. The unrest occurs alongside reported disruption to public transport: Serbia’s state rail operator cancels train services to and from Belgrade, a move that is described as occurring despite the demonstration going ahead. The reports from the different outlets describe the same core events—large crowds demanding early elections, the police response using teargas and stun grenades, and the continued running of the protest alongside rail cancellations. The coverage does not indicate a final outcome for arrests or injuries within the provided excerpts.
