A large 14-storey tower block on the outskirts of Paris was demolished in a matter of seconds on Wednesday.

However, a sudden change of wind direction blew a cloud of thick dust from the site towards nearby onlookers.

The building, which was in the commune of Vitry-sur-Seine, was the last of three similar ones to be demolished in recent years.
