A fast-moving wildfire in California continues to grow in size. The firefighters said that they struggle through sweltering temperatures. A state of emergency was declared in Mariposa County on Saturday and will allow the state to access some federal assistance to tackle the fires.

California’s Fire Department said last night that the Oak Fire has now burned 15,603 acres of land and is still zero percent uncontained. The fire activity is not as extreme as on previous days and firefighters are making progress.
