A young Saudi woman who caused a sensation by defying her family and seeking asylum abroad was welcomed with open arms in Toronto on Saturday at the end of an exhausting international odyssey.

Foreign Minister Chrystia Freeland greeted Rahaf Mohammed al-Qunun, 18, after she landed in Toronto, wearing a blue ball cap and a gray hoodie emblazoned in red with the word “CANADA.” Smiling broadly, she posed for photographers with Freeland at her side, but made no statement.

“She had a pretty long journey and is exhausted and prefers not to take questions for the moment,” Freeland said.

Qunun captured the world's attention with a trail of Twitter posts that ignited a #SaveRahaf movement as she fled what she said was an abusive family in ultra-conservative Saudi Arabia.

Thai authorities backed down on an attempt to deport her after she arrived in Bangkok on a flight from Kuwait a week ago, turning her over to the US's refugee agency instead.

Then on Friday, Prime Minister Justin Trudeau made the surprise announcement that Canada would take her in. The move is sure to further strain Canada's relations with the kingdom.

That relationship went sideways last August over Ottawa's rights criticism of Saudi Arabia, prompting Riyadh to expel the Canadian ambassador and sever all trade and investment ties in protest.

Canada also sparked fury in Riyadh by demanding the “immediate release” of jailed rights campaigners, including Samar Badawi, the sister of jailed blogger Raif Badawi, whose family lives in Quebec.

Qunun's attempt to flee Saudi Arabia was embraced by rights groups as a beacon of defiance against repression.

'Precarious situation'

“Ms al-Qunun's plight has captured the world's attention over the past few days, providing a glimpse into the precarious situation of millions of refugees worldwide,” said Filippo Grandi, the UN High Commissioner for Refugees (UNHCR).

“Refugee protection today is often under threat and cannot always be assured, but in this instance international refugee law and overriding values of humanity have prevailed.”

Raif Badawi's wife Ensaf Haidar also praised Canada, calling Freeland on Twitter “the real hero” behind efforts to prevent Qunun's repatriation to Saudi Arabia.

Qunun alleged that she was abused by her family — who deny the allegations — and rights groups also said she had renounced Islam, risking prosecution in Saudi Arabia.

Qunun first said she was aiming for Australia, where officials had suggested they would give serious consideration to her claim for asylum, which was endorsed as legitimate by the UNHCR on Wednesday.

But late Friday Thailand's immigration police chief Surachate Hakparn said a smiling and cheerful Rahaf was bound for Toronto and had left on a flight after 11pm (1600 GMT).

“She chose Canada ... (and) Canada said it will accept her,” Surachate told reporters at Bangkok's main airport. “She is safe now and has good physical and mental health. She is happy.”

Qunun left from the same airport where her quest for asylum began in a swift-moving process that defied most norms.

Death threats

On Friday afternoon Qunun posted a cryptic tweet on her profile saying, “I have some good news and some bad news.” Her account was deactivated shortly afterward in response to death threats she had faced, her friends said.

But she was back online later in the day, tweeting: “I would like to thank you people for supporting me and saving my life. Truly I have never dreamed of this love and support.”

Qunun's skillful use of Twitter saw her amass tens of thousands of followers within a week, highlighting her plight at a time when Saudi Arabia's human rights record is under heavy scrutiny following the murder of journalist Jamal Khashoggi last year.

Her deployment of social media allowed her to avoid the fate of countless other refugees who are quietly sent back home or left to languish in Bangkok detention centers.

She refused to see her father, who traveled to Thailand and expressed opposition to her resettlement.

Surachate said her father and brother were due to return home on a flight in the early hours of Saturday.

Although Qunun's asylum case moved quickly, the final maneuvers that led to her flight to Canada remain largely a mystery.

Surachate had told reporters earlier Friday that “two or three” countries were ready to offer her asylum.

The Southeast Asian country is not a signatory to a convention on refugees, and asylum seekers must be referred to a third country.
