Thousands of students blocked traffic at Autokomanda, one of Belgrade's busiest intersections, for 24 hours to protest the Serbian government's failure to prosecute those responsible for the collapse of a concrete canopy at the main railway station in the northern city of Novi Sad in November.

Serbia's striking university students on Monday launched a 24-hour blockade of a key traffic intersection in the capital, Belgrade, stepping up pressure on the populist authorities over a deadly canopy collapse in November that killed 15 people.

One of Belgrade's key traffic arteries turned into a campsite on January 27. Thousands of students and citizens gathered for an all-day road blockade, demanding political and criminal accountability for the deaths of 15 people at Novi Sad's railway station on November 1.

The move was aimed at stepping up pressure on the authorities over a deadly canopy collapse in November last year that killed 15 people.

Thousands of citizens joined the blockade that followed weeks of protests demanding accountability of the deadly accident in the northern city of Novi Sad that critics have blamed on rampant government corruption.
