Authorities say two people are dead from an Encino apartment fire that also left a firefighter and five other people hospitalized.

The Los Angeles Fire Department says more than 100 firefighters fought the blaze that was reported about 9 p.m. Thursday.

When crews responded, a unit in the three-story building was in flames, but firefighters managed to squelch the blaze in about an hour.

NBC4 reports that the two people killed were an elderly mother and her son. They lived in a third floor unit in the three-story building. Smoke inhalation is the likely cause of death but an official cause of death will be determined by the coroner.

Some of the fire alarms in the building may not have been functioning properly, according to NBC4.

The building was equipped with a "pull system" fire alarm that was operational, but no one activated it, LAFD Capt. Jaime Moore said. Hard wired smoke alarms were found in both the units and hallways, but did not appear to be functional.

Five other civilians required hospitalization. A firefighter was treated for a hand injury and listed in fair condition.

No names were immediately released.

The cause of the blaze is being investigated.
