British authorities on Wednesday warned people with heart or lung conditions to avoid exertion as a combination of industrial pollution and Sahara dust blankets the country in smog.
The environment department said the air pollution level could reach the top rung on its 10-point scale.
The department said the smog was caused by pollution from Britain and industrialized areas of the continent staying in place because of light winds, along with dust blown up from a storm in the Sahara desert.
