The smog in Moscow is getting thicker.
Moscow is the capital of Russia.
Airborne pollutants such as carbon monoxide is at six times the normal levels.
So the Russians and the tourists need to wear masks to protect themselves.
The smog got inside the buildings in Moscow.
The State Historical Museum, on Red Square was forced to close because it couldn’t stop its smoke detectors from going off.
The smog is so thick that we can’t see very far away.
Some flights to Moscow’s Domodedovo and Vnukovo airports had been diverted to other airports.
There could also be road accidents because the drivers can’t see clearly in the thick haze.
The fires drew comment from officials and activists at international climate-change talks in Bonn, Germany.
There are natural disasters all over the world.
I think the people in Moscow should avoid going outside because the thick smog can cause accidents and the air quality is very low.
