Prince Harry says he cried once after Diana death
In a new interview clip promoting the publication of his autobiography Spare, Prince Harry recounts how he and Prince William were unable to show any emotion as they met mourners in public, Qazet.az reports.
He told ITV's Tom Bradby he had cried when his mother was buried.
The Duke of Sussex said he had felt "some guilt" walking among crowds who left flowers outside Kensington Palace.
The absence of Princess Diana in Prince Harry's life is highlighted as a theme throughout Spare.
The book is not due to be published until 10 January, but extracts were leaked after some copies went on sale early in Spain. BBC News has obtained a copy and has been translating it.
In the ITV interview, due to be broadcast on Sunday evening, Prince Harry said "everyone knows where they were" when his mother died in a car crash in Paris in August 1997.
He said he had looked back on the footage of him and his brother meeting mourners a few days later.
