Video footage showed major structural damage to the building in Solidarnost, a village 400 km (250 miles) south of Moscow, and rescue workers on the scene, attempting to clear the rubble. Six other people were injured, the TASS news agency reported, citing Vasily Razmunov, head of the local emergencies ministry. The regional branch of Russia's Investigative Committee said a gas explosion in the central part of the building had caused it to collapse. Investigators said they had opened a criminal case on the grounds that services provided had not met safety requirements. Gas explosions are relatively common in Russia because of ageing infrastructure and poor safety regulations surrounding gas use.
