Kemerovo, The Gulf Observer: At least 20 people have died in the city of Kemerovo, Siberia after a private residence caught fire early on Saturday morning. Dozens of firefighters and emergency crews managed to contain the blaze.

The building reportedly belonged to a pastor of a local Protestant church, and was being improperly used as a homeless shelter for the elderly.The fire was detected around 3:30am local time.

Some 28 vehicles and 80 firefighters were dispatched to handle the flames. Initial reports spoke of 11 deaths, but that number has since increased to at least 20.

The victims appear to be the elderly residents of an unregistered homeless shelter, an Emergency Ministry official told Interfax.

At the moment, the authorities suspect the fire was caused by an electrical malfunction, as “the wiring probably could not handle that many heaters,” the official said. The undocumented nursing home reportedly did not have any fire-suppression systems, normally required of legally registered institutions.
