A series of deadly blazes in care homes hit Russia in the past years, highlighting safety lapses in state-run institutions.

In February 2009, Russian President Dmitry Medvedev ordered comprehensive checks in all Russian retirement homes to uncover possible safety violations and to look into general living conditions after 23 people, most of them elderly persons, died in a fire that destroyed a wooden care home in the Republic of Komi in northwest Russia.

In a similar incident in June 2007, at least 10 people were killed and four seriously injured in a fire at a retirement home in West Siberia.

The deadliest incident took place in the Krasnodar region in southern Russia in March 2007, where 63 pensioners and medical staff died in a fire at a retirement home.
