Creek Fire: Helicopters rescue dozens of trapped California campers.

Helicopters have rescued more than 200 people trapped after a wildfire set 45,000 acres alight and cut off a popular reservoir in California, officials say.

About 20 of the people were hurt, some with burns.

The Creek Fire began on Friday in the Sierra National Forest, cutting off the Mammoth Pool Reservoir, 40 miles (60km) north-east of Fresno.

The temperature has hit 47C (117F), part of a record heatwave in the state.

The fast-moving Creek Fire started at about 18:45 on Friday (01:45 GMT on Saturday) in the forest, an area of steep and rugged terrain.

National forest spokesman Dan Tune said he did not know how close the fire was to the campsite, a popular boating and fishing destination.
