Forensic experts in New York say they have identified body parts of two of the 10 hijackers who flew planes into the World Trade Center on 11 September 2001.
Ellen Borakove, a spokeswoman for the New York Medical Examiner's Office, said the identifications had been made using DNA samples provided by the Federal Bureau of Investigation (FBI).
The FBI had collected the DNA from tiny traces of skin on the steering wheels of vehicles hired by the hijackers and from hair samples recovered from their hotel rooms.
Earlier this month, the FBI provided profiles of all 10 hijackers, including alleged ringleader Mohammad Atta, so their remains could be separated from those of victims.
"No names were attached to those profiles. We matched them, and we have matched two of those profiles to remains that we have," Ms Borakove said.
"We haven't finished our work, so it may be more," she added.
