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.

Government minister Goran Vesic said he would tender his resignation, after 14 people died on Friday at the Novi Sad train station. This follows major protests calling for the government to take responsibility.
