One person was killed and 12 others were injured, six of them critically, after a building collapsed Wednesday afternoon at the edge of a construction site in Brooklyn, the Fire Department of New York said.

The collapse occurred around 4 p.m. near the intersection of Bedford and Flatbush Avenues in the Flatbush neighborhood, the department said. The building appeared to have been three stories tall, with a business on the ground floor, and stood next to an excavation where a one-story structure had been demolished. Debris spilled into the construction pit.

Firefighters pulled people from the rubble as a search continued into the evening, using dogs and working by flashlight after dark. The city’s Department of Buildings said inspectors were at the scene to help with recovery and to check nearby buildings. An investigation into the cause was ongoing, officials said.
