2-alarm fire destroys Mid-City church

New Orleans firefighters are investigating a Wednesday morning fire that burned down an old church in Mid-City.

Fire officials say the former Jehovah's Witness church located at Banks and Salcedo Streets starting blazing around 3:30 a.m.

With 43 fire personnel on the scene, they had it under control in just over 45 minutes.

A neighbor, Elvis Lazo, said he heard an explosion before the fire started.

"I was in the back of the house," Lazo said, "I could still feel the heat from across the street."

The fire is under control, but officials expect firefighters to be out all morning. There are no reported injuries at this time.

An Entergy spokesperson says about 100 customers were without power in the immediate area. Power lines were damaged in the fire.

During the incident a firefighter was treated for heat exhaustion and stayed on the fire scene.  Once he was back in quarters he felt ill again and was transported to the hospital.  He is currently being treated at a local hospital.

The cause of the fire is still under investigation
