As many as 17 suspects pending trial were reportedly sent to jail by a Turkish court on Tuesday due to their involvement in last week's Ataturk airport attack, which claimed 45 lives and wounded hundreds of people.
The number of those arrested in connection with the attack has gone up to 30 with the arrest of these suspects, 11 of whom are foreigners. Thirteen people were remanded to custody on Sunday, Reuters reported citing state-run Anadolu Agency.
The latest arrests were on charges of "membership of an armed terrorist organization," the agency reported citing Dogan news agency.
Two of the suspected bombers are reportedly from Russia. A Turkish official said that the attackers hailed from Russia, Uzbekistan and Kyrgyzstan.
Three bombers opened fire at the Ataturk airport last Tuesday. Two of the bombers entered the airport and blew themselves up, while the third set off the bomb at the entrance of the international arrivals terminal.
Officials believe that the suicide bombing was carried out by the Islamic State group.
Last Tuesday's airport attack in Turkey was the deadliest suicide bombing carried out in the country this year.
