According to the first information from the Turkish media, Erdogan blamed Greece and Cyprus for the tension.
In fact, the same information states that the Turkish president took a particularly tough stance towards the German Chancellor and insisted on his positions.
Erdogan reportedly told the Merkel that “the selfish and unjust attitude of Greece and the Greek-Cypriots is supported by some countries, which is unacceptable”.
Following my discussions with Greek & Turkish leaders, the two Allies have agreed to enter into technical talks at #NATO to establish deconfliction mechanisms and reduce the risk of incidents & accidents in the #EastMed. https://t.co/Kc70MlNPzY
