The mayor of Fermoselle, where the fire started on Wednesday, gave the number of hectares and told AFP the village faced "hell" and a "tunnel of flame" in the blaze, which follows days of larger wildfires west of Madrid.

Emergency services for the Castilla y León region said 800 people were evacuated from the path of the new blaze.

Spain's Military Emergency Unit (UME) was deployed to the Level 2 fire -- a classification that triggers extra support from the central government.

Raul de la Fuente, a senior fire official in the Castilla y León regional government, said the fire was burning through a ravine and threatening to reach another village, with strong winds forecast.

"We are focusing our efforts in stopping that from happening," he told reporters.

Two other Level 2 fires — at Val de la Loba and San Cipriano del Condado -- were active in the same Zamora province, in the Castile and Leon region which has already been hit by the largest fire in Spanish history since record-keeping began.

That fire in the Ávila area has burned approximately 50,000 hectares (125,000 acres) of land.
