This is a story of one fire which happened in a town near Moscow. There are a lot of such wooden houses all over Russia. These houses are for a few families and you may say only poor people live there but it's a big fraction of Russian families still live in such wooden old houses, without a hot water and gas supply.
And also if somebody is getting on fire then all the house is risking to be burned to ashes. Also according to the comments you would be able to see how fast are Russian firemen.
On the picture above you can see the start of the fire. None seem to care - none sees the fire so probably nothing special is going on, maybe some cooking.
