Law enforcement officials are investigating reports of suspicious packages on cargo planes in Philadelphia and Newark, N.J.
Transportation Security Administration spokeswoman Kristin Lee says the planes landed safely and are being swept by law enforcement.
The planes have been moved to a remote location so law enforcement officials can investigate.
Philadelphia International Airport spokeswoman Victoria Lupica says Philadelphia police and other agencies are with a plane at a remote part of that airport. Video from the airport shows emergency vehicles around a UPS jet.
A spokeswoman for United Parcel Service Inc. did not immediately know what prompted authorities to search the flight at Philadelphia. The company says it is working closely with authorities.
