LOS ANGELES (AP) — Los Angeles firefighters have knocked down a major emergency fire that engulfed a Hollywood commercial building.

The blaze reported just after 7 a.m. Tuesday burned so fiercely for a time that firefighters were ordered off the roof and also retreated from the interior, fighting the flames from the outside with streams of water from hoses on ladder trucks.

Fire Department spokeswoman Katherine Main says nearly 150 firefighters battled the blaze for more than 90 minutes before it was extinguished. Main says no injuries have been reported.

Deputy Chief Joseph Castro says nobody was in the pre-1933 building when firefighters arrived and all the businesses were closed.

The mixed-use building is on Santa Monica Boulevard east of Hollywood Forever Cemetery and west of U.S. 101.
