Severe wildfires raging in a Siberian region of Russia have engulfed more than 600,000 hectares of forest, local authorities have warned. In the Eastern Siberian territory of Zabaykalsky Krai, a federal-level state of emergencies has been in place since late April, Russian state news agency TASS reported. Despite huge efforts to tackle wildfire outbreaks in the region, which borders Mongolia, 49 forest fires continue to burn, with a total area exceeding 629,000 hectares, the Russian Ministry of Emergency Situations said Wednesday. Since the beginning of this year, more than 1.4 million hectares of land have been affected by wildfires, according to figures from Russia’s Federal Agency for Forestry published on Tuesday, about three times the total area affected by fires in the United States and Canada so far this year combined.
