NEW YORK (AP) — Heather Mills McCartney spoke out Thursday against Paul McCartney and the tabloid press for not stopping articles that she says have resulted in death threats against her.

"All I can say is when we first split, I said to Paul, 'I'm going to be crucified. ... You know why we split. You know the truth. They don't need to know the details, but you need to stand up and say, "I'm responsible for the breakdown of this marriage,""' Mills McCartney said on NBC's "Today," one in a series of interviews with US morning talk shows.

"If you say that, I'll walk away with nothing, and we'll do a very gentle and quick divorce. And he promised he'd do that. I have evidence of that. And he did nothing," Mills McCartney said.

Mills McCartney broke her silence Wednesday about issues surrounding her divorce case with the former Beatle in interviews on British television. She said that the police told her "serious death threats" had come from an underground movement.

Mills McCartney was asked Thursday whom she thought was behind the threats.

"Well, I can't say who I think it is because it will affect our family, but I know a lot of information, and, you know, certain people don't want certain things coming out because of their image," she told NBC.

McCartney declined to respond to the British interviews.

Mills McCartney took issue with the British tabloid press for "putting front page news about divorces instead of front page news about global warming and important issues."

"And the problem in England is with the libel, there is a cap on cost and damages. So they will get six months of abusive lies front page news out of you, and then they will only have to pay $50,000 to $100,000 damages. ... In the meantime, they've created devastation everywhere, and you get an apology the size of a postage stamp," she said.
