(NewsNation) — A small plane crashed in Philadelphia, causing an explosion and multiple house fires.

Police say two people were on board the plane. The status of those individuals is unknown. Other injuries have been reported on the ground, and multiple homes are on fire.

The FAA said in a statement “a Learjet 55 crashed around 6:30 p.m. local time on Friday, Jan. 31, after departing from Northeast Philadelphia Airport. There were two people on board. The plane was en route to Springfield-Branson National Airport in Missouri.”

Gov. Josh Shapiro said he is offering all “Commonwealth resources as they respond to the small private plane crash in Northeast Philly.”

Flight data showed a small jet taking off from the airport at 6:06 p.m. and disappearing from radar about 30 seconds later after climbing to an altitude of 1,600 feet.

It is not clear what led to the crash.
