New York building collapse: Several insect pesticide canisters, so-called 'bug bombs,' were found in an apartment inside the Chinatown location. Four firefighters were among the injured in the New York building collapse.
An explosion inside a Chinatown building on Thursday led to a fire and a partial collapse, injuring a dozen people, including firefighters.
Three of those injured were hospitalized in serious condition. Injuries to the other people, including the four firefighters, were less severe and included burns.
Fire officials said several pesticide canisters, or so-called bug bombs, were found in the first floor rear apartment and may have exploded, but the cause of the blaze hadn't been determined. Investigators were also looking into a possible gas leak.
