The recent Washington fires are considered the worst in the state's history, according to fire officials, with firefighters from Australia and New Zealand now being brought in to fight the blaze.

Four thousand people have volunteered to help the professional firefighters in combating the inferno. Members of the Washington National Guard have also been set out to help in the effort. The fires grew by more than 26 square miles on Sunday and are expected to spread even more in coming days 

Lastly, about 50 highly trained Australians and New Zealanders, whose native wildfire season is six months away, flew across the globe to lend a hand, according to the Daily Mail UK.

The fires have claimed the lives of at least three firefighters and destroyed 200 homes. The burning in Washington's Okanogan County near the Canadian border where a group of five fires were raging out of control became the worst in the history of the state, leaving 400 square miles of land completely damaged, according to FOX News.

The Okanogan complex of wildfires in the north-central part of Washington State has already exceeded the record-breaking Carlton fires from last year.

Rick Isaacson, a spokesman for crews battling the blazes, said the fires could burn for several more months 

As of Monday, the fire, which is only 10 percent contained, had fully-grown to more than 250,000 acres. More than 1,200 people were displaced by the fires and that the Red Cross has lend its hand on giving momentary housing.

U.S. President Barack Obama has granted state Governor Jay Inslee's request for a federal declaration of emergency, where federal funds will be released to help Washington pay for the cost of combating the fires, Agence France-Presse reported.
