Turkish authorities have deported a French national who was detained at Istanbul's Sabiha Gökçen airport on suspicion that he planned to join the ISIS group in Syria.The officials said that the man arrived at Sabiha Gökçen airport from Milan on Thursday, and was deported back to Italy after he confessed that he had planned to join a terror group in Syria.The man, identified only by his initials B.T., is the latest European to have been detained in Turkey on route to Syria following increased cooperation between Turkey and European governments to stop the flow of foreign fighters to Syria.Thousands of foreign fighters from all over the world are believed to have joined terrorist organizations, including ISIS, in Syria and Iraq.Turkey has been doing its part to identify and deliver potential foreign fighters who are seeking to cross the border to Syria to join ISIS, despite little cooperation in intelligence sharing from Western countries. So far, Turkey has deported over 1,200 people before they could join the terrorist group in neighboring Syria. Turkey has also issued exclusion bans on 12,519 suspected individuals to date, demonstrating its success in blocking the passage of potential fighters heading to join ISIS via Turkey.
