Saudi Arabia just threatened Canada with a 9/11-style attack

Saudi Arabia's state media on Aug 6, 2018, tweeted a graphic appearing to show an Air Canada airliner heading toward the Toronto skyline in a way that recalled the September 11, 2001, terrorist hijackings of airliners that struck the Twin Towers and the Pentagon.

The graphic warned of "Sticking one's nose where it doesn't belong!" and included the text: "As the Arabic saying goes: 'He who interferes with what doesn't concern him finds what doesn't please him.'"

Last week, Global Affairs Canada tweeted that it was "gravely concerned" about a new wave of arrests in the kingdom targeting women's rights activists and urged their immediate release. Saudi Arabia has expelled Canada's ambassador and frozen all new trade and investment with Ottawa in response to the criticism.

Fifteen of the 19 hijackers in the September 11 attacks were Saudi citizens. The organizer, Osama bin Laden, came from a prominent Saudi family and still has family there, including a son who the bin Ladens say is looking to "avenge" his father.

The tweet came from @Infographic_ksa, an account that had just hours earlier tweeted another graphic titled "Death to the dictator" featuring an image of the supreme leader of Iran, Saudi Arabia's main regional rival.

Saudi Arabia has long stood accused of funding radical Muslim Imams around the world and spreading a violent ideology called Wahhabism. Under the leadership of its new young ruler, Mohammad bin Salman, Saudi Arabia has undertaken several sweeping reforms looking to reduce the funding for and spread of radical ideology as well as to elevate human rights.

But a surge of arrests appearing to target prominent women's rights activists who previously campaigned to abolish Saudi Arabia's ban on driving for women has caused international alarm and prompted the tweet from Canada.

The Saudi account deleted the tweet featuring the graphic with the plane and later reuploaded one without the airliner pictured.
