Large crowds of flag-waving protesters converged after meeting up at several agreed-on protest venues in various parts of Belgrade, which was placed on high alert.

The protest in Belgrade, Serbia, was the culmination of four months of rallies against President Aleksandar Vucic’s government after a deadly train station canopy collapse.

While the government put attendance at 107,000 across Belgrade, an independent monitor said 325,000 - if not more - had gathered, making it Serbia's largest protest ever. The Novi Sad collapse last November has galvanised anger towards the government and President Aleksandar Vucic.
