WARNING GRAPHIC VIDEOS AND AFTERMATH
A small plane crashed into several homes in north-east Philadelphia on Friday evening, according to videos and reports.
Two people were aboard the plane and there are reports of others injured on the ground, police said.
Fire officials in Philadelphia said multiple homes are on fire following the crash and explosion. Emergency crews are on the scene.
It is unclear what led to the crash, who was aboard the plane or if there are any survivors.
The plane, a Learjet 55, took off from from the Northeast Philadelphia Airport about 18:30 local time and crashed less than four miles (6.4km) away, according to the Federal Aviation Administration (FAA).
The crash happened just blocks from the Roosevelt Mall, a three-story shopping centre in a densely populated part of Philly.
