Russian authorities started to evacuate two villages in a vast region of Siberia where 155 active forest fires burned on Sunday.
It comes a year after a report highlighted Russia tried to influence voters in the 2016 EU referendum and that the government failed to look into the problem.
The prime minister intervened as the UK vowed to defy the Kremlin and continue travelling through the region.
