A Turkish coast guard vessel crashed twice into a Greek port authority patrol boat six days ago, Kathimerini reported.
The night incident occurred east of the island of Lesvos.
The Greek ship suffered minor material damage.
A similar incident took place in January in the area of the Imia islets.
This comes as a Turkish Coast Guard illegally entered Greece’s territorial waters yesterday and harassed a patrol boat belonging to their Greek counterparts.
