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.

In one of Serbia's largest protests in decades, more than one lakh demonstrators filled the streets of Belgrade. Facing riot police and President Aleksandar Vucic's supporters, protesters voiced their anger over corruption and negligence.

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.
