Greek police said late on Saturday that they had arrested two Greek men on the island of Rhodes on suspicion of spying on Greece.
The police did not specify who the two men were allegedly spying for.
Police said in a statement that one of the men was working for a consulate on the island, while the other was working on a passenger ferry serving a route between the islands of Rhodes and Castelorizo.
A senior police official said that one of the two men was accused of filming the Greek armed forces’ movements in the Aegean Sea.
