New York City: A man killed in the September 11, 2001, attacks in New York has become the 1,638th victim to be identified, the city`s medical authorities said on Monday.
The 49-year-old`s name was not released at the request of his family, the chief medical examiner`s office said. His identification was made possible through the re-testing of remains.
A total of 2,753 people lost their lives in the attacks on New York`s World Trade Center, when al Qaeda hijackers flew two airliners into the Twin Towers.
A third plane was flown into the Pentagon, while a fourth crashed in a Pennsylvania field after its passengers tried to overpower the hijackers.
To this day, just 59 per cent of the victims have been identified, mostly through DNA. No trace has been found of the remaining 41 per cent, or 1,115 people, according to the medical examiner`s office.
Over the years, authorities have recovered 21,906 human remains of which 63 per cent have been identified, it said.
Tests are ongoing in an effort to identify the remaining 37 per cent.
