SILVER SPRING, Md.—Ten people were taken to hospitals, including several people with serious injuries, after an explosion and fire at a Maryland apartment building Thursday morning, a fire official said. Firefighters responded around 10:30 a.m. after 911 callers reported an explosion at the four-story building in Silver Spring, less than a mile north of Washington, D.C., Montgomery County Fire & Rescue Service Chief Scott Goldstein said during a news conference. Crews arriving on the scene found significant fire and evidence of an explosion, Goldstein said. They immediately went to work battling the flames and helped several people get out before the building was completely consumed by fire and there was a collapse, he said. Crews brought 10 people to local hospitals, he said. Several people had serious injuries and others had injuries that were more minor, he said. There were still pockets of fire in the building afternoon, he said. …
