Serbia's students led a mass protest and blocked bridges over the River Danube in the northern city of Novi Sad on Saturday, drawing tens of thousands into the streets to express their anger with the country's populist leadership and to call for change.

Tens of thousands of people blockaded three bridges on the Danube River in Serbia's second city of Novi Sad on Saturday in the latest anti-government protest over a railway station disaster that killed 15 people in November.

Serbian students on Sunday blocked a bridge over the River Danube in the northern city of Novi Sad for over 24 hours as part of their growing anti-graft movement demanding major changes in the Balkan country.

The growing movement began following the collapse of a concrete canopy at the central train station in Novi Sad, killing 15 people.
