A sixth person has died as a result of a passenger train derailment in Philadelphia, a doctor at Temple University Hospital in Philadelphia said Wednesday, Xinhua reported.
Hospitals have treated another 150 people, at least half of whom have been discharged. Among the injured, 25 passengers were being treated at Temple University Hospital, including 8 in critical condition, Herb Cushing, the hospital's medical director, told CNN.
Cushing said that many passengers were injured when other passengers or objects fell on them. Authorities have not ruled out the possibility of more victims from the incident.
An Amtrak passenger train was traveling from Washington, D.C. to New York when it derailed near Philadelphia on Tuesday night. Philadelphia mayor Michael Nutter said that seven cars, including the engine of the train, were derailed. The train was carrying 238 passengers and 5 crew members.
"It is an absolute, disastrous mess," Nutter said. Rescue workers are still searching the scene to find any possible survivor.
The FBI said that so far there is nothing to indicate the incident was an act of terrorism. A National Transportation Safety Board investigation team will arrive Wednesday morning.
White House press secretary Josh Earnest said that the Obama administration is "hard at work" trying to figure out what caused the crash, and that their thoughts and prayers are with the families of everyone effected.
Amtrak said that service between Philadelphia and New York City remained suspended Wednesday.
