Bulldozers clear roads of ash from Chile volcano

Eruptions from a Chilean volcano have left roads and rivers covered in a thick layer of ash.

Wind carried ash across the Andes, dropping a grey blanket on the Argentine resort of Bariloche.

A change of direction then sent ash back to the Chilean side, where bulldozers are trying to clear the debris.
