Five children dead, one missing after Baltimore house fire

The mother of the children killed was injured in the blaze, along with three of her nine children, authorities said. The fire had engulfed the house by the time firefighters arrived on the scene at about 12:30 a.m. EST and its third floor collapsed onto the second floor shortly afterwards, Baltimore Fire Department spokesman Chief Roman Clark said. The five children confirmed killed included a baby, a toddler and 3-year-old twin girls, according to fire officials.
