Soaring temperatures across large swathes of Russia have destroyed nearly 10 million hectares of crops and prompted a state of emergency to be declared in 17 regions.

On Friday the state-run Moscow region weather bureau said it expected the heatwave, which has gripped the country since late June and is estimated to have already cost the agricultural sector about $1 billion, to continue into next week.

Saturday could see temperatures in Moscow hit 37 Celsius (98.6 Fahrenheit), which would break the previous record of 36.6C. set in 1936.

“It looks like tomorrow could just break the record,” the weather bureau’s Moscow head Yelena Timakina said.
