Two people were killed and at least two injured in a fire at a two-story Echo Park apartment building on Thursday morning.

The flames broke out at the 1000 block of Bonnie Brae St. around 12:18 p.m. A 90-year-old woman and a 28-year-old man died, while a man broke his leg jumping out his window and a girl was treated for smoke inhalation, reported KTLA and CBS Los Angeles.

Over 100 firefighters were on the scene and extinguished the fire within 53 minutes. Investigators are checking out the scene and are treating it as a "criminal fire" that was "suspicious in nature," and an accelerant may have been used, reported NBC Los Angeles and CBS Los Angeles.
