A doctor who claims to have been one of the first on the scene as the twin towers collapsed on 9/11 has released a series of unseen photos from the day of the attack.
Dr Emil Chynn, now 50, rushed to the World Trade Center after seeing the Twin Towers burning on September 11 2001 whilst walking his dog.
When Emil, who lives in New York City, arrived at the scene he was surrounded by debris and smoke.
He rapidly got to work setting up what he claims to be the first triage centre on site.
The doctor has now released the photographs he took during the week he volunteered at the scene to demonstrate the kindness of strangers in such a heartbreaking time.

Emil said: "The scene was awful, people were trying to clear debris and body parts from all over the place.
"I quickly did what I could to help and - as the first physician on the scene - set up the first triage centre.
"I was on the scene volunteering for about a week and captured these photos whilst I was there.
"They were captured on a film camera, so took me a while to get them developed, but as soon as I got the physical photos back I knew I had to share them.
"As distressing as the time was and the photos are, they show the pure compassion that people have for other strangers.
"Everyone looks back on what happened in dismay at the human race instead of how a city came together to risk their lives and help people they didn't even know."
