(Newser) – An explosion rocked the Chelsea neighborhood of New York City Saturday night, with reports of multiple minor injuries. The New York Post reports that the explosion took place about 8:30pm in a dumpster outside a Manhattan building that provides services for the blind. (A witness told CNN that it wasn't a metal dumpster but a plastic trash bin of some sort.) In a tweet, fire officials say 25 people suffered injuries, though none appeared to be life-threatening. “It felt like a pipe bomb,” a Mercy College history professor tells the Daily News. Earlier Saturday, a pipe bomb went off in New Jersey before the start of a charity race. Nobody was injured in that incident.
