Gendarmerie and border police have seized dozens of irregular migrants in a rubber boat near the coast of the western province of Aydin, the Anatolian news agency reported on Monday.
It said the forces had seized 49 irregular migrants trying to cross Turkey illegally in Europe.
The detainees were 31 Syrians and 18 Iraqis.
