A woman has claimed she was in the Twin Towers during the 9/11 attacks and said people kept on working after planes hit the buildings. Watch her recount her experience here:
Nena, from the Bronx, New York, said she was working on the 84th floor of 2 World Trade Center during the devastating terrorist attack on 11 September 2001.
Nena was just 21 at the time and said 61 of her colleagues died in the attack.
Remarkably, she claimed some people carried on working after the South Tower had been struck, with the building being the second to be hit and the first to collapse.
Reflecting on the tragic events on her TikTok account - with the 20th anniversary less than two months away - Nena said: "We lost 61 co-workers. Most of them were trying to help everybody out, the other half were still trading, because I was a bond broker on the floor.
"They were still trading and you know, money sometimes comes first. You know, you're not thinking straight. So they stood and traded and they lost their lives.
"So we lost 61 people. Majority of their bodies weren't recovered, but we held memorial services for them. And we do every year, every 9/11, and I don't work on a 9/11."
Nena went on to say that many people reassessed how they view money after that day.
She said: "A lot of us have realised that the folks that did stay behind and trade, it was like, you know, money was great back then, you're thinking it's not gonna affect you.
"It's a building across the street, you know, across the way. It's not gonna affect you, you're chasing that money, chasing that bag, and then your life is over.
"So ever since that day, I live my life to feel like money is not happiness.
"The pay is good, don't get me wrong, but at the end of the day money isn't what makes happiness.
"It's what you feel inside. If you feel safe, you feel good. I could be making $15 an hour and live a happy life. You know what I mean? So it changed a lot of people's perspective and a lot of them did not return to work and moved on."
Having escaped the tower, Nena said she had to walk for eight hours to tell her family she was safe.
She said: "I had to walk and I was covered in dust, covered like in this white powder, and I had to walk eight hours from ground zero to Co-op City in the Bronx.
"When I got there, no cell phones were working. I had to use my house phone - yes, we did have a house phone then - and try to call everybody that I could to let them know that I was OK.
"When they heard my voice they just broke down and cried."
