SAN FRANCISCO (AP) — The Latest on heat and wildfires in the Western United States (all times local): 9 a.m. Firefighters in Los Angeles are working to contain a blaze that chewed through brush-covered mountains just north of downtown, growing to nearly 8 square miles and prompting mandatory evacuations for several hundred homes. Los Angeles Fire Department spokeswoman Margaret Stewart said Saturday that no injuries have been reported and no buildings burned. Heat that has afflicted the entire Western United States made conditions tough for crews, which had contained just 10 percent of the brush fire by daybreak.
