Students in Serbia have blocked a Danube bridge after spending the night in tents and sleeping bags 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.

Wrapped in blankets and huddled around fires at makeshift camps, Serbian students braved subzero temperatures in Novi Sad as they spent the night outside after a mass rally against corruption brought tens of thousands to the streets.
