THOUSANDS of people vowed on Sunday to keep fighting for justice and rule of law in Serbia as they demanded that President Aleksandar Vucic call a snap parliamentary election.

This follows months of demonstrations that have challenged President Vucic’s grip on power.

Protesters led by university students blocked bridges in the capital Belgrade and rallied in 30 other Serbian cities and towns as they also marked exactly seven months since a concrete canopy collapsed at a train station in the north, killing 16 people and sparking the massive wave of anti-corruption protests.

“The whole of Serbia has risen,” protesting students said in a speech that was read out at the rallies. “There will be no more silence, there will be no more surrender!”

Many people in Serbia believe that the deadly November 1 canopy collapse in Novi Sad was the result of flawed renovation work on the station building.

In Belgrade, crowds halted traffic at two key bridges over the Sava River for three hours, while protesters in Novi Sad carried a white wreath for the canopy collapse victims.

President Vucic has accused the protesters of working for unspecified Western powers to “destroy Serbia.” Pro-government media on Sunday described the blockades in Belgrade as “terror.”
