Turkey has arrested and charged 17
more suspects - including 11 Russians - over the bombings which caused
carnage at Istanbul's Ataturk airport last month.
The suspects are accused of involvement in terrorism, Dogan news agency says. Thirteen, including three foreigners, were charged on Sunday.
The organiser of the attack has been named by Turkish media as Akhmed Chatayev, a Chechen believed to have acted as an IS recruiter.
It is not clear where he is now. The Russian news website Kommersant says he has Austrian refugee status and that he lost an arm during fighting in Russia's troubled North Caucasus.
