Volker Schwenck, a TV journalist for public broadcaster ARD, was detained on Tuesday after arriving in Turkey and appears set to be expelled from the country.
Authorities have yet to give Schwenck any reason for refusing his travel into the country, The Local reports, citing ARD’s tagesschau website.
“My travel into Turkey has been refused. There’s a black mark against my name. I’m a journalist. Problem?” the Cairo bureau chief and Middle East expert wrote on Twitter early on Tuesday.
Schwenck had been planning a trip to the Turkish-Syrian border, where he hoped to speak with refugees fleeing the war in Syria.
Turkey’s frontier with its war-torn neighbour have increasingly come into focus in recent days as NGO Human Rights Watch reported that border troops were using live rounds to scare refugees away.
Amnesty International has also accused Turkey of illegally expelling Syrian asylum seekers across the border, forcing them to return to their war-torn country.
“Our colleagues in Ankara and Istanbul are in contact with the responsible Turkish authorities and the person affected,” the German Foreign Ministry tweeted on Tuesday afternoon.
