In total, 17 people have either been jailed or interviewed by Turkish police after the attack, Today's Zaman said. Turkish officials suspect the attack was carried out by elements loyal to Syrian President Bashar Assad in an attempt to escalate Syria's two-year civil war into a larger regional conflict.
Assad's government has denied any role in the bombing.
Celalettin Lekesiz, governor of Hatay province, said four more suspects remain at large.
