Angry protesters have left red handprints in front of government buildings in the Serbian capital to demand the arrest of officials, two days after a concrete canopy collapsed at a railway station, killing 14 people and injuring three.

Serbia wound up a rescue operation and opened an investigation on Saturday into a roof collapse at a railway station in the northern city of Novi Sad that killed 14 people and injured three others. The disaster happened on Friday when a length of roofing along the entrance to the station collapsed.
