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.

The rally on Saturday in the capital, Belgrade, came as protests have spread to towns around the country and have drawn increasingly insistent calls that President Aleksandar Vucic step aside.
