(CNN) A fire raging in Spain's Canary Islands off the northwest coast of Africa has prompted the evacuation of a thousand people, the islands' President Ángel Víctor Torres said on Sunday.

Speaking at a news conference, he said that the affected area was 1,000 hectares (about 2,500 acres). The neighborhoods concerned were from the municipalities of Artenara, Tejeda and Gáldar.

The fire spread on Gran Canaria, the second-most populous of the Canary Islands with just less than 900,000 people.

Earlier on Saturday, firefighters said in Spanish they were "overwhelmed by the situation," adding "we are fighting for our island!!!"
