At least 100,000 people have converged in Belgrade for a massive rally in the Serbian capital seen as a culmination of months-long protests against populist President Aleksandar Vucic.

Tens of thousands of protesters filled the streets of Serbia’s capital over the weekend, the culmination of more than four months of demonstrations against the government of President Aleksandar Vucic and what they see as its slow response to a deadly train station collapse in November.

Tens of thousands of people have descended on Serbia's capital to protest against the deaths of 15 people in a railway station collapse. The government has put attendance at 107,000 across Belgrade. Organisers and independent monitors have yet to give their estimates.
