At least three people are reported to have died after a building under construction collapsed in the provincial town of Saransk, set to host matches during the 2018 World Cup.
Authorities in the town south east of Moscow said earlier in the day that the 10-story building’s stairs had collapsed.
A source in the republic of Mordovia’s regional government told the state-run TASS news agency that three had died in the incident.
The deaths were confirmed by a source in the emergency services to the Interfax news agency.
The incident comes less than one week after several people died when part of an apartment block collapsed in the central Russian city of Izhevsk.
Authorities opened a criminal case into murder, alleging that one of the residents may have deliberately caused a gas explosion.
