A huge fire at a tyre dump in Spain has sent a “toxic cloud” of black smoke into the air, and residents have been told to keep windows and doors shut.
Emergency services were called to the town of Sesena, 35 km (22 miles) south of Madrid, at 01:00 local time (23:00 GMT on Thursday).
They sent 10 teams of fire-fighters, who have battled the blaze all day.
Some schools stayed closed for the day and people with respiratory problems have been advised not to leave home.
There are no reports of any injuries.
El Pais (in Spanish) reports that investigators believe the fire was started deliberately, as recent humid conditions make other causes unlikely.
Drivers on roads nearby have been told to keep their car windows up as the smoke may damage their health.
Flight departures and arrivals at Madrid airport have not been affected.
In 2015 The Guardian newspaper reported that local government authorities were searching for a company to shred and recycle 90,000 tonnes (99,000 tons) of tyres that had been dumped there.
