A house fire in rural Kentucky killed five young children, a pregnant woman and her boyfriend on Saturday, NBC News reported. The man’s uncle raced to the scene to try to save them, but it was too late, The Associated Press reported. "Hey, there's babies in there, there's babies in there!" Gino Cima screamed to firefighters, according to his wife, Laura Cima, who also was at the scene, according to the AP. Laura Cima said she owned the single-story, wood-frame house that the couple rented from her recently in the tiny town of Gray. The woman who died in the fire, was the mother of three of the children, aged 3, 2 and 10 months, while the other two kids were sleeping over, according to NBC News. Relatives told NBC affiliate WLEX-TV the woman was a few months pregnant. All seven died of smoke inhalation. Arson investigators were at the scene Saturday, but officials said no foul play was suspected.
