The Swedish site referred to some of those books and articles published on websites specialized for selling books, including a book by the American-Yemeni terrorist Anwar al-Awlaki, entitled "44 Ways to Support Jihad, al-Qaeda and Daseh."
The book was presented on N11.com as of May 27, 2019, when it was last accessed by Nordic Monitor.
The Criminal Court of the Peace Judge banned this book in Mersin province in southeastern of Turkey near the Syrian border on February 2, 2016.
The judge's order No. 873/2016 prohibited the sale and distribution of al-Awlaki's book; however, N11.com allowed its platform to sell the book in defiance of the rule.
The N11.com website was established in 2012 in Istanbul as a joint venture among the Doğuş Group, a business group in support of Recep Tayyip Erdoğan.
Al-Awlaki is believed to be the cleric who inspired the Major Nidal Malik Hasan, the gunman in the November 5, 2009 shooting fire that killed 12 US soldiers and a doctor at the Fort Hood Military Base in Texas.
Omar Farouk Abdul Mutallab, the Nigerian man who tried to blow up a Northwest Airlines plane while landing in Detroit on Christmas Day 2009, he was one of al-Awlaki's students.
Al-Awlaki was killed in a US drone attack in 2011.
According to an investigation by Nordic Monitor, N11.com uses its platform to sell other extremist books, for example, the book entitled "Lovers of Paradise Virgins," written by Abdullah Yousef Azzam, a Palestinian and founding member of al-Qaeda was offered for being sold on the site.
Azzam, described as the father of global jihad, contacted with Turkish youths through translating works such as this book, which commemorates more than 150 terrorists, who died during the Soviet presence in Afghanistan and he was killed in 1989.
The judge's order also banned the sale and distribution of al-Awlaki's book, which Azzam wrote on the banned books list. However, many sellers have listed the book for sale on N11.com, and some have even offered it at discounted prices.
Unlike the jihadist books, which are freely distributed in Turkey, Erdogan's government suppresses journalists, authors and publishers who have participated in the production of legitimate works that criticize it. There are nearly 200 journalists behind bars in Turkey on trumped-up terrorism charges to date, while the government has seized more than 150 media outlets, publishing houses and libraries on charges of participating in the production of cash publications.
