California wildfire explodes near Yosemite and Sierra national parks – video

A blaze erupted in California on Friday and quickly grew to 11,900 acres (4,800 hectares) in size as the state's governor, Gavin Newsom, declared a state of emergency for the Yosemite area. More than 2,000 people were fighting the Oak fire along with helicopters, other aircraft and bulldozers. The blaze blocked one of the main routes into Yosemite, where this month a stand of huge, ancient sequoias was threatened by a wildfire that began near the Washburn Trail. That fire burned 4,857 acres and is now about 80% contained. The Oak fire was already more than twice the size of the Washburn blaze
