A house explosion killed a girl and injured her parents and brother Thursday morning in Oklahoma City, authorities said.
The cause of the blast was not immediately known, but officials said it does not appear intentional.
The child, whose age has not been released, was pronounced dead at the scene. Her father was taken to the hospital in serious condition and her mother and brother sustained burn injuries, according to the city’s fire department.
When emergency responders arrived at the scene around 7 a.m., the fire was already out and the house was “completely leveled” with debris spread all over the street, said District Fire Chief Benny Fulkerson.
The explosion also damaged at least three other houses in the neighborhood and could be heard miles away.
“My mom says she was awoken to a massive blast — her bed shaking and her whole house rattling,” ABC News correspondent Erielle Reshef, who said her parents live 6.5 miles away from the site, wrote on Twitter.
“What a powerful explosion this must have been,” she said. “Such a tragedy. Sending love home to this family.”
“Please join me in praying for this family during this unimaginable tragedy,” he wrote.
Officials said the home had propane, not natural gas, and that the Oklahoma Corporation Commission would take over the investigation.
Speaking to reporters outside the property Thursday, a visibly emotional Fulkerson said it is always “tough” to respond to fatal incidents involving children.
“Well, unfortunately, we see it in our line of work,” he said. “It’s never easy. It’s something that we hate to see, but we’re here to help when we can.”
