Four Turkish nationals appeared Friday before a prosecutor in Orestiada, northeastern Greece, after being arrested Thursday in a forbidden military area in Evros, the river border separating Greece from Turkey.
According to reports, two of them told Greek authorities that they were journalists and that they had crossed into Greek territory while reporting on the case of the Turkish woman and her three children who went missing after their boat capsized in the Evros river.
The other two said they were relatives of the missing.
No more information was immediately available.
A search and rescue operation along the Evros River continued Friday.
