A medevac plane crashed soon after takeoff in Philadelphia on Friday with a child and five others on board, the air ambulance company that operated it said, adding that it had not confirmed any survivors.

Philadelphia's mayor says five people hurt on the ground when a jet crashed Friday remain hospitalized, and three of them are in critical condition.

A seventh person has died after a small plane crash Friday night in Philadelphia, while all six people who died aboard the medical transport aircraft were identified Sunday.
