Paris offers free public transport to reduce severe smog-
Ministers acted after air pollution exceeded safe levels for five days running in Paris and surrounding areas. The smoggy conditions have been caused by a combination of cold nights and warm days, which have prevented pollution from dispersing. The elderly, children, asthmatics and people with heart problems have been advised to stay indoors to avoid potential breathing problems.
On Friday, public transport was made free of charge for three days in an attempt to encourage people to leave their cars at home. This measure continued on Monday.
The capital's air quality has been one of the worst on record, French environmental agencies say, rivalling the Chinese capital, Beijing, one of the world's most polluted cities.
