U.S. President Joe Biden declared an emergency in California and ordered federal assistance to boost local responders' efforts to battle the Caldor fire, the White House said on Wednesday.
The fire has been burning in the Sierra Nevada range since mid-August and still threatens homes and businesses near Lake Tahoe, abetted by gusty winds and bone-dry conditions.
Biden's action authorises co-ordination of disaster relief measures by the Department of Homeland Security and Federal Emergency Management Agency (FEMA), the White House added.
