Briton, Greek soldier held in border area on spying charges Greek authorities have brought espionage charges against a British national working for a charity assisting migrants and a Greek soldier, who were arrested together in a military area on the border with Turkey

THESSALONIKI, Greece -- Greek authorities have brought espionage charges against a British national working for a charity assisting migrants and a Greek soldier, who were arrested together in a military area on the border with Turkey.

Police had originally sought that the two men aged 25 and 29, who were arrested Sunday, should face lesser charges of entering a restricted military area without permission.

But on Monday, a prosecutor in the northeastern town of Orestiada charged them with espionage, because a photograph of military facilities was allegedly found in the men's possession, together with other pictures of the border area.

The 29-year-old Greek army sergeant served in a border unit and was off-duty at the time of his arrest.

The Evros area is a key crossing-point for migrants entering Greece illegally from Turkey.
