The breach was monitored by the Greek navy and coast guard, the Kathimerini newspaper reported.
The Aegean dispute has been a major source of tension between Greece and Turkey since the 1970s, bringing the two countries to the brink of military confrontation in 1987 and 1996. The dispute revolves around a set of issues involving the delimitation of territorial waters, airspace, demilitarized zones and the status several Aegean Sea islands.
Talks to resolve the issue began after 1999, when Turkey agreed to resolve the bilateral dispute as part of its accession deal with the European Union.
Tensions were again stoked last month, when a Turkish missile boat approached the islet before being blocked by the Greek coast guard. The incident took place after Greek Supreme Court’s ruling against the extradition of eight Turkish soldiers involved in a failed coup against the Turkish government last year.
