A German newspaper says a Greek photographer who was working for it has been turned back by Turkish authorities at Istanbul's main airport.
The Bild daily reported that Giorgos Moutafis was prevented from continuing to Libya on Saturday evening. He had to take the next plane back to the Greek capital, Athens, on Sunday morning.
It quoted the photographer as saying he had been told at passport control that his name was on a list of people who weren't allowed to enter Turkey, but wasn't given a reason why.
The reported incident comes days after a journalist with a German public broadcaster was prevented from entering Turkey. Chancellor Angela Merkel says she discussed that case during a visit to Turkey on Saturday.
