A man who died of cancer due to breathing in toxic dust following the collapse of the World Trade Center in New York on September 11, 2001 has become the latest addition to the attacks' overall toll.
The death of Leon Bernard Heyward brings the overall death toll from the terror attacks to 2,752.
Mr Heyward, 45, died on October 18, 2008 from "lymphoma complicating sarcoidosis", the New York City medical examiner's office said.
Mr Heyward's is the second name to be added to the list in the years following the attacks.
Officials in May 2007 also linked the death of Felicia Dunn-Jones five years earlier to dust she inhaled at the World Trade Center site in New York.
The cause of death for all the official victims of the attacks is homicide, a spokesperson for the medical examiner said.
