At least six people were killed in the collapse of a five-storey apartment bloc in the Russian city of Nizgnevartovsk, a spokesman for the local emergencies agencies told TASS on Sunday.
"Two more bodies have been found. In all, the death toll is six," the spokesman said, adding that clear-up operations continue and there could be more people under the debris.
The accident took place in a five-storey apartment on Sunday. Officials revealed that the Inter-floor structures collapsed between the first, second, and third floors.
Fifty-two people were evacuated and ten were saved.
Based on preliminary data, the collapse was caused by a household gas explosion due to the mishandling of a gas cylinder. Its fragments were found in the debris. The house is not connected to the centralized gas supply system.
