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.
