Parisian officials have been forced to take drastic steps after the city was revealed to be suffering its worst winter pollution for at least a decade.

For the third day running, all public transport in the city, and in the 22 communes of La Petite Couronne, has been made free to use, and certain vehicles have been banned from entering the city.
