Smog alert called in Prague and four other regions


Meteorologists have called a smog alert in Prague and four other regions, as conditions worsened around the country. The concentration of dust particles in the air is exceeding permitted levels several-fold. Drivers have been asked to use public transport to help alleviate the situation. Should it worsen the authorities could ask the biggest polluters to temporarily scale down production. A smog alert is now in effect in eight regions altogether.
