Firefighters are attacking a brush fire burning in a canyon area of Laguna Niguel.
The fire burned at least 3 acres in Aliso Woods Canyon. Water-dropping helicopters are part of the response.
Details about how the fire started at roughly 3 p.m. were not immediately available.
The fire is burning below a neighborhood at the top of the canyon.
The area is between Aliso Viejo and Laguna Niguel. Smoke could be seen for miles along the Orange and Los Angeles county coasts.
