A river in southern Chile has overflowed is banks, after it was blocked by volcanic ash and mounting debris. The area around the Nilahu river has been evacuated as a result.

The raised water levels follow the eruption of a volcano in the city of Puyehue on Saturday, which sent a huge ash cloud across nearby towns and all the way to Buenos Aires, the capital of neighbouring Argentina.

The ash has also damaged swathes of crops and killed many fish.
