ADVERTISEMENTMADRID — The suspected cause of a raging wildfire in northeastern Spain is the combustion of improperly stored chicken manure in high heat.
Hundreds of firefighters struggled Thursday to contain the blaze that has spread over 5,500 hectares (13,590 acres) and forced the evacuation of 53 residents.
A Spanish military unit with 120 specialists joined local firefighters who had worked overnight to control the blaze that sent thick plumes of smoke over difficult, hilly terrain near the Ebro River.
Miquel Buch, the regional interior minister, said 20,000 hectares were under threat in what is the worst fire in the Catalonia region in two decades.
Buch said authorities suspect the cause of the outbreak was a deposit of improperly stored chicken manure at a farm in the village of Torre de l'Espanyol that high temperatures caused to combust.
Television images showed horses and sheep incinerated on a farm that had stood in the path of the fire.
Five roads were closed to traffic in the rural area which is about 120 kilometers (75 miles) west of Barcelona.
The fire comes amid a heat wave that is boosting temperatures across Europe.
Firefighters said that temperatures over 30 degrees Celsius (86 degrees Fahrenheit), low humidity, and high winds fanned the flames.
