At least 100,000 people descended on Belgrade on Saturday for a mass rally seen as a culmination of months-long protests against Serbia’s populist President Aleksandar Vucic and his government.

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.

Serbian anti-corruption protesters, riot police, and supporters of President Aleksandar Vucic faced off in central Belgrade on Saturday as tens of thousands of people turned out for massive anti-government rallies following a night of sporadic clashes.
