By Tatyana Kekic in Novi Sad Serbia is in the throes of a political crisis, sparked by a deadly infrastructure collapse in Novi Sad late last year, with ongoing student-led protests putting immense pressure on the government.

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.

Three months after the collapse of the awning at the local train station, which claimed 15 lives, the anger in the country is still not dying down, despite the resignation of Prime Minister Milos Vucevic.
