Thousands of Serbs marched to mark one month since the collapse of a concrete train station canopy that killed 15 people in the city of Novi Sad, with youth groups joining a procession from the station to central Freedom Square on December 1. During the walk, marchers stopped 15 times and silently paid respects to each of the 15 fatalities. Red paint representing blood was spread as "red messages" to the authorities. The November 1 incident has turned into a political headache for President Aleksandar Vucic and his ruling party, with protesters demanding those responsible be held accountable. The accident occurred after the railway station, built in 1964, had been renovated twice in recent years by a Chinese-led consortium. To read the original story by RFE/RL’s Balkan Service, click here.
