 Saudi Arabia's Foreign Ministry responded on Twitter saying "KSA through its history has not and will not accept any form of interfering in the internal affairs of the Kingdom." A Saudi Arabian organization is apologizing after posting an image on Twitter appearing to show an Air Canada plane heading toward the CN Tower in a way that is reminiscent of the 9/11 attacks in the U.S. 
 
 "As the Arabic saying goes: 'He who interferes with what doesn't concern him finds what doesn't please him,'" reads a caption superimposed over the image. "The ministry has ordered the owner of the account to shut it down until investigations are completed," read the tweet. Last Tuesday, the Office of the UN High Commissioner for Human Rights said at least 15 human rights defenders and women's rights activists critical of the Saudi government had been arrested or detained arbitrarily since 15 May. Saudi Arabia ordered the Canadian ambassador to leave the country and recalled its own ambassador on Sunday after Global Affairs Canada sent a tweet expressing "grave concern" over the recent arrests of civil society and women's rights activists and calling for their "immediate release." Saudi Arabia would also "put on hold all new business and investment transactions with Canada while retaining its right to take further action", it said. It is unclear how many people this will affect.
– Saudi Arabia shut down the Twitter account of a government-linked youth group after it escalated the kingdom's dispute with Canada by appearing to threaten a 9/11-style attack on Toronto. The Infographic KSA site posted an image of an Air Canada plane flying toward the CN Tower, with the caption "As the Arabic saying goes: 'He who interferes with what doesn't concern him finds what doesn't please him,'" reports the CBC, which notes that 15 of the 19 hijackers on 9/11 were Saudis. The image also had the phrase: "Sticking one's nose where it doesn't belong," an apparent reference to the Canadian government's statements supporting detained Saudi women's rights activists. Before it was shut down pending a Saudi media ministry investigation, the youth group apologized, claiming that the image of the plane was supposed to represent Canada's expelled ambassador arriving home. Beyond kicking out the ambassador, Saudi Arabia, denouncing Canadian "interference" in its affairs, has canceled the national airline's flights to Toronto, frozen new investment in Canada, and ordered 15,000 Saudi students not to attend Canadian universities, Al Jazeera reports. But Ottawa is standing firm, with officials saying they "will continue to advocate for human rights" and call for the release of detained activists, including Samar Badawi, sister of jailed dissident Raif Badawi, reports the BBC.
