Russian authorities say out-of-control agricultural fires have killed at least 15 people, injured hundreds more and destroyed or damaged more than 1,000 homes in Siberia.

The fires were started by farmers burning the grass in their fields, but spread quickly because of strong winds.

The health ministry in Khakassia, a region in southeastern Siberia, said on Monday that 15 people including a child have been confirmed dead and 393 people were injured.

Emergency officials said early morning that they have put out the fires in all 38 villages in the area with the help of aircraft and 6,000 firefighters.

The region's chief, Viktor Zimin, said in televised remarks that it would take about 5 billion rubles ($94 million) to rebuild housing in the area.
