TENS of thousands streamed into a central square in Serbia’s capital today for a rally against populist President Aleksandar Vucic and his government, whose tight grip on power has been challenged by weeks of street protests led by university students.

The rally at Belgrade’s Slavija Square, one of the largest in recent years, was called by students and farmer unions. It was part of a wider movement demanding accountability over the November 1 collapse of a canopy at a railway station in the country’s north that killed 15 people.

Smaller rallies were also held in the cities of Nis and Kragujevac. The rally in Belgrade started with a 15-minute silence for the victims, and later chants of “You have blood on your hands!” were heard.
