In an effort to control dangerous levels of pollution, the Italian city of Milan is set to ban vehicles from the street on Sunday - for up to 10 hours, the BBC has reported.
The measure was first implemented on a trial basis in 2007, and is now brought in to control whenever city pollution rises above normal limits for 12 consecutive days.
Milan is one of Europe's most polluted cities.
Over 12,000 vehicles will be affected by the move, the BBC quoted the Corriere della Sera newspaper.
