Warning: This story contains graphic details of the aftermath from the 9/11 attacks.
On 11 September 2001, photographer and documentary filmmaker Paul Berriff was living and working in New York City.
He was caught up in the 9/11 attacks and still remembers the day in vivid detail.
More recently, he has become one of thousands of survivors to be diagnosed with terminal illnesses connected with the long-term effects of that day.
Now aged 80 and living near Northallerton in North Yorkshire, Berriff has recalled the events.
“Somebody came into the office and said a plane had hit the twin towers,” he said.
First thinking it was likely to be a light aircraft or helicopter, often seen flying around the landmark, he phoned his wife who was at their home in Lower Manhattan.
She told him about “fire engines and people running around” and his “news instinct kicked in” and he travelled to the scene to document the events on camera.
As Berriff, a sound recordist and assistant producer approached, they could see “both towers were on fire”.
“We could see these black dots coming down from the side of each building and we wondered what it was,” he said.
“As we got nearer, we could see it was people jumping, so we knew it was pretty serious.”
They headed to the base of the towers, where assistant fire commissioner Steve Gregory was sending firefighters in.
