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. <br /><br />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.<br /><br />The ash has also damaged swathes of crops and killed many fish.<br /><br />Craig Mauro reports from the Chilean city of Puyehue.
