'She'd be proud of Harry and I.' Princes William and Harry open up about the death of their mother, Princess Diana

Princes William and Harry have spoken candidly about the death of their mother, Princess Diana, in an interview marking 20 years since she was killed in a car crash in Paris, paying tribute to the actions of their father in breaking the tragic news.

Excerpts of the BBC interviews released Wednesday mark something of a departure for the two princes, who have largely refrained from discussing Prince Charles' actions in other interviews describing their mother ahead of the anniversary. But in the documentary "Diana, 7 Days," they appear to offer sympathy for him, quelling speculation that he had been uncaring in the crisis.

"One of the hardest things for a parent to have to do is to tell your children that your other parent has died," Harry said. "How you deal with that I don't know but, you know, he was there for us."

The documentary chronicles the week after the princess' death on Aug. 31, 1997 and features then-Prime Minister Tony Blair, senior royal aides and Diana's brother. The princes have spoken out for a series of programs and interviews in the run-up to the anniversary, sharing personal insights into their lives in keeping with their campaigns to promote mental health.

The two brothers discussed the funeral, with a now balding Prince William describing how he hid behind his bangs to keep out the prying eyes of sobbing crowds. He described the procession as a "very long, lonely walk," even though understood there was a balance "between me being Prince William and having to do my bit, versus the private William who just wanted to go into a room and cry, who'd lost his mother."

"I just remember hiding behind my fringe basically, at a time when I had a lot of hair, and my head's down a lot — so I'm hiding behind my fringe." William, who was 15 at the time, said "it was kind of like a tiny bit of safety blanket if you like. I know it sounds ridiculous, but at the time I felt if I looked at the floor and my hair came down over my face, no one could see me."
