Five villages were evacuated as flames devoured hills that are 375 kilometers (230 miles) northeast of Madrid, said Javier Lamban, the president of Aragon. The evacuees, who included residents of a retirement home, were transferred to nearby towns.
Some 500 firefighters and 26 aircraft were fighting the flames today, which were being fanned by windy conditions and were creating a large plume of smoke.
The fire, which broke out yesterday afternoon, has already burned more than 2,500 hectares (6,180 acres) of forest in a remote area, according to Ministry of Agriculture and Environment spokesman Modesto Lobon.
