Spanish officials have ordered the evacuation of 9000 people from a large apartment complex after a raging fire at tyre dump sent spectacular, toxic clouds of black smoke into the sky.
The tyre dump is located in Sesena, a central town near Madrid. It is thought to be the largest tyre dump in Europe.
About 70 per cent of the tyres had burned by Friday night but authorities did not know when the blaze would be completely extinguished.
No injuries were reported because of the fire, which authorities believe was intentionally set.
The smoke plume was visible from Madrid, more than 30 kilometres away.
Classes at one school were cancelled and authorities urged drivers to keep their windows closed.
