After spending a freezing night out in the open, hundreds of striking students resumed their two day anti-graft protest march from the capital, Belgrade, to the northern city of Novi Sad, where they plan to blockade three bridges over the River Danube this weekend.

The bridge blockade is planned for Saturday to mark three months since a huge concrete construction at the railway station collapsed in Novi said on November 1, leaving 15 people dead.
