Paris chokes for second day
PARIS authorities restricted traffic in the city for a second day after a "lid of pollution” sealed the capital, causing concern over public health. Photographs showed a grey veil of dirty air trapped over the city, masking the horizon and, at times, landmarks such as the Eiffel Tower. Experts said it was the longest, most intense spike in pollution for at least 10 years and was expected to continue for at least another day. The spike in pollution was blamed on anticyclonic conditions, and people turning up their gas heating or lighting fires.
