NEW ORLEANS (AP) — New Orleans officials say 11 construction workers were injured when a one-story house collapsed during renovations.

New Orleans Emergency Medical Services spokesman Lt. Jonathan Fourcade says every worker on the site was injured, but all were able to walk.

He does not know details about their injuries, but says four were taken to a hospital trauma center.

The accident occurred about 10:40 a.m. Thursday in New Orleans’ 7th Ward.

A photograph showed only the front wall, three columns and the roof over the brick front porch still standing. The left side wall appeared to have fallen sideways, and part of the roof was leaning at a sharp angle against the facade.
