US: Philadelphia fire kills at least 13, including seven children
Eight people managed to evacuate themselves from the house
New York: Thirteen people, including seven children, died when a fire tore through a converted three-story house in the eastern US city of Philadelphia on Wednesday, officials said.
Philadelphia Fire Department deputy commissioner Craig Murphy said the toll was "dynamic because there is still an ongoing recovery effort inside."
Two additional people were rushed to hospital, he added.
The fire officer said that it was the worst fire he had seen in 35 years on the job.
Murphy said it was too early to say what caused the blaze but that his department was conducting an investigation.
"It's not necessarily considered suspicious but we have all hands on deck because of the magnitude of this fire," he told reporters.
"We're in the process of investigating this to the highest level that we can. We're incorporating all of our resources."
He said that there were four smoke detectors in the building but "none of them" had been operating.
The building is owned by Philadelphia's public housing authority.
Eight people managed to evacuate themselves from the house, Murphy said.
