And the Emergency Situations Ministry in Tatarstan, a republic in central Russia, said a toddler and two adults were killed in a house fire on Sunday in Kazan, the main city.
Another two adults died and three children were injured on Sunday when a dormitory caught fire in Peresvet, a town in the Moscow region, RIA Novosti said.
Fire safety rules are often violated in Russia as a result of corruption, with officials often granting building permits in exchange for bribes.
