The four Turkish citizens, whose visas have been annulled by the Bashkir Interior Ministry, worked in that shop. They are: Ozer Ibrahim Denia, the founder of the Stil firm; Ashgenaa Hairetdin, its executive director; and Aktepe Yusuf and Uailashkan Shahin, deputy directors.
According to the Interior Ministry, when militiamen checked the shop, they found out that banned literature was being spread among its clients.
The spokesman for the ministry said that the works of the sect's founder, Said Nursi, and his follower Gullen have been banned even in Turkey where the Nurdjular supporters are trying to overthrow the secular government and replace it by a sharia government.
According to the data of international intelligence agencies, the Nurdjular sect is connected with the Grey Wolves terrorist organisation and has about 300 schools and universities in 35 countries.
In the past two years, more than 20 followers of the Nurdjular sect, citizens of Turkey, were deported from Russia.
