Jan 31 (Reuters) - A medevac plane crashed 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.

Jet Rescue Air Ambulance said its aircraft crashed with four

crew members, one pediatric medical patient and the patient's

escort on board.

"At this time we cannot confirm any survivors," the company

said in a statement.

President Donald Trump wrote on social media that it was "so

sad to see the plane go down in Philadelphia, Pennsylvania. More

innocent souls lost. Our people are totally engaged. First

Responders are already being given credit for doing a great

job."

The crash follows this week's collision of an American

Airlines ( AAL ) jet and a U.S. Army Black Hawk helicopter over

Washington, D.C., which killed 67 in the deadliest airplane

crash in the U.S. since 2009.

The Federal Aviation Administration said six people were on

the Learjet 55 that crashed around 6:30 p.m. (0030 GMT). Local

media reported it was near the Roosevelt Mall in northeast

Philadelphia and that there were multiple injuries on the

ground.

Video aired on local TV stations showed the plane in a sharp

dive before slamming into the ground in a heavily populated area

of northeast Philadelphia and exploding in a massive fireball.

At least one house and multiple cars were on fire, the

Philadelphia Inquirer reported. The weather was cold and rainy

and with low visibility at the time of the crash.

The air ambulance had left Northeast Philadelphia Airport

and was headed to Springfield-Branson National Airport in

Missouri, about 1,100 miles (1,800 km) to the southwest, the FAA

said in a statement.

Philadelphia Mayor Cherelle Parker told a press conference

at the scene of the crash that she did not have information on

numbers of victims. The situation is "all hands on deck, that's

where we are right now," she said.

A large fire and several fire trucks were visible at the

crash scene in images broadcast by the Philadelphia CBS

affiliate. The station said the status of victims was not

immediately known.

About two hours after the crash the fires were mostly out,

according to TV images.

The Philadelphia Office of Emergency Management said on

social media there was a "major incident" in the area of the

reported crash but provided no other details.

Neither the Philadelphia police department nor the fire

department immediately responded to requests for comment.

Pennsylvania Governor Josh Shapiro wrote on social media,

"We are offering all Commonwealth resources" as first responders

work at the scene of the crash.
