The U.S. State Department advised Greece and Turkey to show restraint in the Aegean Sea after the tension near Inousses, a cluster of islands.
On Friday, a Turkish Navy boat harassed a Greek fisherman near Inousses. At the same time, a CN-235 aircraft flew above the island at a very low altitude (up to 200 feet), violating Greek airspace.
The Greek defense ministry has answered by placing a small army unit on the nearby Passas islet.
Similar violations and provocations have been very frequent in the area after the European Union-Turkey agreement that was signed in March for stemming migrant flows from Turkey to Greece.
Ankara makes territorial claims in the area and tries to include the Inousses island cluster in the grey zones.
In light of the violations, the U.S. State Department called on Greece and Turkey – both NATO allies – to resolve their differences and cooperate in order to maintain stability in the wider region.
