People in many areas of the Czech Republic have been advised by the fire brigade to keep their windows closed as they fight a big forest fire.
Reports say, parts of the Bohemian Switzerland national park, which sits on the German border, have been burning since last Sunday.
Amid record temperatures and dry conditions, strong winds have sent the smoke drifting across the country.
According to reports, homes have been destroyed and the smell of smoke has reached the capital Prague one hundred kilometer to the South.
Smoke has also been detected in the Pardubice area, one hundred and eighty kilometer to the South-east.
