The Greek Foreign Ministry complained over Turkish harassment of an Italian ship in international waters overseen by Athens, AFP reported Wednesday. The Italian ship was exploring a possible fiber optic route from Italy to Israel, and had received Greek permission to explore the waters near the Aegean island of Crete."The Italian vessel was harassed by a Turkish corvette in violation of the rules of international law," AFP quoted a Greek foreign ministry official as saying, adding that the Greek embassy in Ankara issued a demarche on the events to Turkish authorities, defining the Turkish harassment as illegal.
