Hayley reports on the high air pollution levels

High levels of air pollution are expected across parts of the UK today, in particular in the South East and eastern England.

Warm, still conditions combined with traffic fumes, pollution from Europe, and dust from the Sahara in Africa to create the problem.

The government has issued a warning over the levels of pollution.

On a pollution scale of 1-10, a level 10 is likely in some parts - the highest level of air pollution.

Weather experts said that while no regions have reached the highest level of air pollution so far, six regions hit a level of pollution up to level 9.

These are eastern England, south-east England, Greater London, West Midlands, East Midlands, and Yorkshire and Humberside.

Air pollution forecast for Friday

The elderly and those who have lung problems have been told to avoid doing heavy exercise outside.

However, the pollution will be brief and levels will drop lower by the weekend.
