Ahead of the 20th anniversary of Princess Diana’s death, the late royal’s sons Princes William and Harry opened up about the moment they learned their mother had died, while criticizing the people who did not help the Princess of Wales in the backseat of her car after her accident inside Paris' Pont d'Alma tunnel.

"I think one of the hardest things to come to terms with is the fact that the people that chased her into the tunnel were the same people that were taking photographs of her while she was still dying on the backseat of the car," Harry said in a BBC documentary, Diana, 7 Days. "And William and I know that we’ve been told that numerous times by people that know that was the case.”

Meghan Markle’s boyfriend continued, “She’d had a quite severe head injury, but she was very much still alive in the backseat and those people that caused the accident, instead of helping, were taking photographs of her dying in the backseat, and then those photographs may have made their way back to news desks in this country."

William, 35, and Harry were holidaying at Balmoral with their father Prince Charles when they learned of their mother’s death. "I remember just feeling completely numb, disorientated, dizzy," Prince William recalled. "You feel very, very confused. And you keep asking yourself 'Why me?' All the time, 'Why, what have I done? Why, why has this happened to us?'"

Harry praised his father for protecting him and his older brother after the passing of Diana. ”One of the hardest things for a parent to have to do is to tell your children that your other parent has died," the 32-year-old said. "How you deal with that, I don’t know. But, you know, he was there for us. He was the one out of two left, and he tried to do his best and to make sure that we were protected and looked after. But, you know, he was going through the same grieving process as well.”

Following the death of Princess Diana, Harry admitted that he no longer want to be a Prince. "Years after, I spent a long time in my life with my head buried in the sand, thinking, I don't want to be Prince Harry, I don't want this responsibility, I don't want this role. Look what's happened to my mother, why does this have to happen to me," he confessed.

Though now he and William look to carry on their mother’s legacy. "Now all I want to do is try and fill the holes that my mother has left, and that's what it's about for us is trying to make a difference and in making a difference making her proud," Harry said. "She was the Princess of Wales and she stood for so many things, but deep down inside for us she was a mother. And we will miss our mother and I wonder every single day what it would be like having her around."
