At least 4 hurt in explosion at Dallas apartment building, officials say

A large fire and possible explosion at a Dallas apartment building promoted a massive response from Dallas Fire-Rescue on Thursday afternoon.

DFR dispatch records show the response is in the area of East 9th Street and North Patton Avenue, which is just east of the Bishop Arts neighborhood, north of the Dallas Zoo and south of downtown.

Video from CBS News Texas Chopper shows a severely damaged building with flames and thick black smoke pouring from the wreckage. 

In a statement, Dallas Fire-Rescue said the fire was the result of a reported explosion, but the details are still unconfirmed. Nearly 100 firefighters are on the scene, with the first call coming at 12:47 p.m.

One person has been taken to a hospital, DFR said, but the number could change depending on how many people were home at the time of the incident.

CBS News Texas has crews responding to the scene.

This is a developing story and will be updated.
