A three-story building in the Flatbush area of Brooklyn collapsed Wednesday afternoon, killing several people, including at least one child, officials said. As of 8 p.m. ET, police officials did not have a full account of how many people were still trapped, CNN reported. The building on Bedford Avenue in Flatbush collapsed into an adjacent construction and excavation site, News 12 Brooklyn reported. It said at least 10 people were taken to the hospital, with four of them in critical condition. Rescuers pulled several people from the rubble, including a pregnant woman whose husband told reporters she was alive. The area is largely residential. The building held a store at ground level and at least one apartment upstairs, CNN said. The New York Fire Department called the effort "a major technical rescue response" and asked people to avoid the area. In another post, city emergency management said it and the Red Cross have opened a reception center for residents of the building at the Flatbush YMCA. The city Department of Buildings said it is investigating the collapse. Department records show
