A fast-moving wildfire has swept across the Angeles National Forest in southern California in the United States.

Thousands of campers and hikers had to flee after the fire spread quickly in the dry weather conditions.

The blaze, dubbed the Tecolote fire, burnt at least 350 acres (142 hectares) of the forest in three hours.

Air tankers and helicopters have been deployed to contain the fire but officials have said there is no threat to lives or buildings.
