A concrete roof above the entrance of a railway station in the northern Serbian city of Novi Sad collapsed on Friday, killing at least eight people.
Interior minister Ivica Dacic said that at least four other people have been admitted to hospital with serious injuries, while rescuers have established contact with two people who are still buried under piles of concrete.
Ambulances and other emergency teams were sent to the central station and bulldozers were removing the debris as people looked for survivors.
Surveillance camera footage showed people moving in and out of the building and sitting on benches as the concrete structure suddenly collapsed on them.
The building has recently been renovated.
