Greece has sent a letter of complaint to NATO and the United Nations over Turkish President Tayyip Erdogan's inflammatory statements and demanding that Ankara's behavior be condemned, Reuters reported, citing diplomatic sources.
Earlier, the European Union expressed concern over President Recep Erdogan's statements in which he accused Greece of occupying demilitarized islands in the Aegean Sea and threatening an attack.
Turkey's state-run Anadolu news agency said Ankara sent letters this week to the European Union, NATO and the UN explaining its position and views on the disputed issues.
Sources in Greek diplomatic circles said Wednesday that Turkey's letter distorted reality and that its arguments were unfounded and violated international law. Greece has also sent letters to the U.N. and NATO, they said.
Turkey's position is a destabilizing factor for NATO unity and cohesion, weakening the North Atlantic Alliance's southern flank at a time of crisis, Greek Foreign Minister Nikos Dendias said in a letter to NATO Secretary General Jens Stoltenberg.
