Hospital wants probe into slain Swedish minister's treatment.

The Stockholm hospital where seven years ago Sweden's foreign minister died of her wounds after a knife attack said Wednesday it wanted a review of her treatment because of a media investigation.

They wanted to determine if more could have been done to save Anna Lindh's life, said a spokesman.

But he stressed that the hospital did not believe any mistakes had been made in their treatment.

"We have just sent the request to the National Board of Health and Welfare," Klas Oesterman, a spokesman for the Karolinska University Hospital in Stockholm told AFP.

"There is a television news team that has asked us questions about Lindh's treatment ... and we understand that they are planning a piece criticising her treatment," Oesterman said.

"We have not seen any signs, then or now, to indicate that we made any mistakes, but we want an independent investigation," he added.

Lindh's murder "is a question of such national importance and interest (that) we don't think this question should just be tossed out in a television programme," he said.

The foreign minister was stabbed repeatedly in the arms, chest and abdomen by a man with a history of psychiatric problems as she shopped at the upmarket NK department store in Stockholm without a bodyguard on September 10, 2003.

She died of massive internal bleeding some 13 hours later, in the early hours of September 11.

It remained unclear how long it would take for the health and welfare board to reach a conclusion, but Oesterman said he hoped to have an answer "within a few days."

Swedish media reported that it was the commercial TV4 channel that was planning a story on Lindh's hospital treatment.

Lindh's killer Mijailo Mijailovic, now 32, is serving a life sentence for the murder.

The killing of the 46-year-old mother of two young boys sent a shockwave around Sweden, bringing back painful memories of the still-unsolved 1986 assassination of prime minister Olof Palme.
