Workers at JFK report package made them ill

NEW YORK (AP) — The FBI is testing a substance in a package at John F. Kennedy International Airport in "an abundance of caution" after two customs workers reported they felt ill after opening it Sunday.

FBI spokesman J. Peter Donald said the two Customs and Border Patrol employees will be screened as well. The FBI testing is following some initial testing that indicated a possible cause for concern.

The Port Authority of New York and New Jersey, which oversees the airport, didn't respond to a call seeking comment.

Customs and Border Patrol referred questions to the FBI.
