More than 20 people have been diagnosed with a bacterial disease with one child dying in a Siberian region.
An outbreak of anthrax in the Yamalo-Nenets region has claimed the lives of 2,300 reindeer and has now killed a 12-year-old child.
This is the first fatal outbreak in Russia in 75 years with recent heatwaves encouraging the disease to spread.
Deer herding families have been evacuated from the affected areas as troops trained for biological welfare have been sent in to help with the emergency.
90 people are currently being checked for the disease in hospital says a local governor with 50 of them being children.
It is reported that all reindeer have now been vaccinated.
