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 rally was part of a nationwide anti-corruption movement that erupted after a concrete canopy collapsed at a train station in Serbia's north in November, killing 15 people.

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.
