Eighteen months ago, the renovation of the railway station in Serbia’s second biggest city, Novi Sad, led to a tragic accident. A substantial concrete canopy, which ran across the front of the station building, suddenly collapsed, killing sixteen people. The disaster sparked mass protests. Marchers demanded justice for the dead and injured. As the protests spread, to the capital, Belgrade, and to towns and cities across the country, the demands evolved. Protesters accused the government of corruption and of covering up the truth about what happened. The government accused the protesters of being foreign agents, supported and organised by malign outside forces. Now, after more than a year, the mass protests have finally subsided. Jill McGivering is in Serbia to find out what’s happened to that explosion of anti-government anger.
