Iranian investigators are blaming a misaligned missile battery and miscommunication between soldiers and their commanders for the Revolutionary Guard shooting down Ukrainian jetliner in January, killing 176 people including 55 Canadians.

Authorities had initially denied responsibility, only shifting their message days later after other countries presented extensive evidence that Iran had shot down the plane.

"This is [a] continuation of the lies and deceit they have been doing, and we don't believe anything, what they say, because they're not credible. They have lost their credibility," Doustshenassaid.

"If they have nothing to hide why are they holding the black boxes for six months?"

'This is not simply an error'

Doustshenas, who is also the president of the Victims Families PS752 Association, is calling for a "credible investigation" involving international bodies,and he wants Canada to pursue a criminal investigation as well.

"The [Iranian] regime has worked very hard the past six months to divert all attention to the black boxes and meanwhilethey're trying to create their own narratives that this was just a human error which is not true," he said.

"This is not a simply an error, this has to be pre-planned at many levels and they have to prove what they're saying, but they're not coming up with any proof."

Doustshenas says he and Khadem were planning on getting married in June and were about to start their new life when she died.

"She was a beautiful, a smartvery accomplished scientist. She was ready to help whoever needed help and she was always [smiling]," she said.

"She was the love of my life. I never imagined at this stage of my life I'm going to find someone so beautiful and so loving and then to be snatched brutally. It's devastating my life."

'Handicapped' in dealing with crash

In the wake of Iran's report, former foreign affairs minister and Manitoba member of parliament Lloyd Axworthysays Canada should have a representative in the country's capital to help get answers and challenge the report.

"I think we've been handicapped in dealing with the consequences, the outcomes of the crash itself in terms of compensation, in terms of being able to make representations because we don't have any diplomatic or consul representations in Tehran,"he said in a Skype conversation with CBC News on Sunday.

Officials in Iran say the country will transfer the plane's black boxes to France, and investigators from Canada and other countries are going next weekto see if any data can be retrieved.

"When we're not there we're simply relying upon other governments to do the lifting for us and I think that's why it's important to get involved," Axworthy said.

He addedCanada needs to restore its diplomatic relationship with Iran, which stopped in 2012, and was something the Liberals promised to do if elected.

In a statement from Global Affairs Canada, the federal government said it'scalling for Iran to act immediately to conduct a thorough investigation.

"Canada will continue to actively work with its international partners to hold the Iranian regime to account and to ensure Iran follows through on its commitments, including the download of the data and voice recorders at France's Civil Aviation Safety Investigation and Analysis Bureau on July 20th," the statement said.

"Canada and its partners will continue working to ensure transparency, accountability, justice, compensation and closure for the families of the victims of this terrible tragedy."

Doustshenassays he won't rest until he gets justice for his fiance.

"I have no life other than pursuing the truth and finding justice for her and others."
