"We know that she was murdered and not the victim of an accident," the minister said in Toronto. Canada has not given up on the case and will enlist international support against Iran, Pettigrew added.

"We will be continuing to work with the international community, put the pressure on Iran so that they render justice," he said.

Stockwell Day, the Tory foreign affairs critic, suggested the recall of Canada's ambassador and the imposition of sanctions, but Pettigrew wasn't enthusiastic. Canada needs an ambassador in Tehran to keep the pressure on, he said.

"I don't believe much in individual or bilateral sanctions but this is the kind of thing that we can discuss with the international community."

Alexa McDonough, the NDP foreign affairs critic, said the government must pursue "new measures" to see justice done.

"It must be open with Canadians and Ms. Kazemi's family as to the nature of these measures, be they direct measures with Iran, within the United Nations or both," she said.

Refugee doctor Shahram Azam, formerly with the Iranian military, spoke with clinical coolness at an Ottawa news conference earlier Thursday, methodically listing a tally of bruises, broken bones and other injuries he found on Kazemi. These could only have been the result of the deliberate torture and rape, he said.

Kazemi, 54, an Iranian-born dual citizen, was arrested after taking pictures outside a prison in Tehran in June 2003.

Speaking through an interpreter, Azam recounted in a matter-of-fact way how Kazemi was brought into his Tehran hospital unconscious and on a stretcher on June 27, 2003, four days after her arrest.

Azam, a former major in the Iranian security force, arrived in Canada on Monday. He fled Iran last summer with his wife and daughter under the guise of seeking medical treatment.

Officials from the Foreign Affairs and Immigration departments interviewed him in Sweden in November and fast-tracked his claim for refugee status.

Reading from notes he said he made when he examined Kazemi, Azam said he found horrendous injuries, ranging from a broken nose and finger bones to head and body bruises, a ruptured ear drum, lash marks, torn-off fingernails and toenails and feet beaten blue.

He said as a male doctor in a military hospital, he was banned from examining a woman's genitals, but the nurse who did so told him of "brutal damage."

"As a doctor, I could see this was caused by torture," Azam said.

Iranian officials have said she died after she went on a hunger strike, fainted and struck her head as she fell.

"This was not an accident," Pettigrew scoffed.

Azam recited his findings in a calm, detached manner, gesturing to describe the location of some of the worst bruises.

He said a CAT scan that night showed bleeding in the brain and he learned the next day his patient was brain dead. The incident shook him.

"It was the first time I saw a patient brought in from a prison," he said. "It was so shocking for me."

He said he had to come forward to tell his story freely because "I am a human being."

Marlys Edwardh, lawyer for the family, said Azam's recollections match the description given by the women's mother, who was allowed to briefly view the body in the hospital.

She said his account also makes it clear the Iranian government has lied about the case from the start.

Kazemi's son, Stephan Hachemi, who has kept his mother's case in the public eye for months, watched expressionless from the audience as Azam delivered his grisly findings.

Hachemi kept his emotions under tight rein as he said he's disappointed with the Canadian government's lack of progress in getting justice for his mother.

"I'm continuing what my mother has started by standing up to the Iranian regime," he said.

Edwardh said the family wants Prime Minister Paul Martin to press Iran for a full criminal investigation of the case. Iran put a low-ranking official on trial last year, but he was acquitted after a hearing that was seen as a sham.

Edwardh said the government should press for international mediation and compensation for Kazemi's family.

Pettigrew said officials will meet the family's lawyers to discuss all options.

"The family needs answers, Canadians want answers and we will not stop pursuing this case until justice is rendered," he said.

Martin, who said his officials will meet Hachemi, condemned the Iranian behaviour.

"By any standard, this is simply unacceptable."

Justice Minister Irwin Cotler said in Montreal that his officials are looking at what actions Canada might pursue.

"We're going to look at the legal options that are available to the Canadian government," he said.

Hachemi said all Canadians have a stake in his mother's case.

"It's everybody's responsibility," he said. "It's not a personal matter, it's a national matter, it's an international matter."
