CNN reports that smoke clouds, which have become a serious health hazard, can clearly been seen on the satellite images, blanketing large swaths of the country.

The smoke is back in Moscow, which hasn't seen rain or cool weather in two months. The promised departure of heat meant only the drop in temperatures from 100-115 F down to 90-95 F. The fires have killed more than 50 people, left dozens hospitalized, and thousands homeless, according to Russia's health and social development ministry.

"Russia is grateful to the United States over the assistance in tackling the wildfires raging across the country," said the Russian Foreign Ministry. According to CNN, the United States sent some $4.5 million in aid that included water tanks, pumps, hand tools, fire-protective clothing and medical kits, according to the U.S. State Department.
