A row house partially collapsed in Northwest Washington, D.C., on Monday morning, trapping a worker inside, D.C. officials said.

The rear of a two-story row home in the 1100 block of V Street NW crumbled, and the worker was "severely trapped," D.C. Fire and EMS officials said in a statement on social media.

Photos show debris piled near a building that looks destroyed from the back and first responders in D.C. Fire and EMS uniforms climbing over rubble.

"Patient is trapped under bricks," an emergency dispatcher can be heard saying on audio of a call to authorities.

Crews are working to rescue the trapped worker and secure hazards, D.C. Fire and EMS said.
