At least 192 undocumented migrants, including women and children, were held in the southern Mersin province, security sources said Sunday.
Turkish Coast Guards detained 165 Syrians traveling in a boat in the Mediterranean Sea, said the sources who refused to be named due to restrictions on speaking to the media.
They included 63 children and 30 women.
Following their interrogation, the coast guards detained 27 other foreigners.
Separately, a van driver suspected of human smuggling was arrested.
Turkey has been the main route for migrants trying to cross into Europe, especially since the beginning of the civil war in Syria.
