Crowds of protesters are gathering in Belgrade for a massive rally in the Serbian capital seen as a culmination of months-long protests against populist President Aleksandar Vucic.

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.

A huge protest took place in Belgrade, marking the peak of more than four months of student-led demonstrations against President Aleksandar Vučić. It is the biggest challenge to his 11-year rule, which is accused of becoming increasingly autocratic.
