A small medical jet carrying six people crashed in a Northeast Philadelphia neighborhood Friday evening, officials said, causing an explosion and setting several homes ablaze. It's unclear if anyone aboard survived.

Officials said they could not yet confirm how many people may have died on the ground after the plane slammed into a heavily populated portion of the city.

Shriners Children's said the child on board had received care and was being taken back to her home country of Mexico, along with her mother, when the crash happened.
