United States Ambassador to Athens Geoffrey Pyatt expressed Washington’s support for Greece following the new provocative action by Turkish President Recep Tayyip Erdogan, photographed at the National Defence University of Istanbul in front of a map showing Turkey’s borders extend halfway into the Aegean Sea.

The map, titled “Turkey, Blue Homeland”, showed Turkey’s maritime borders extending 462,000-square kilometres into the Aegean, including Greek islands.

“I wouldn’t worry too much about the maps,” said Mr Pyatt.

“Greek sovereignty is unquestionable and certainly recognised by the United States,” Mr Pyatt said in response to journalist questions on the sidelines of a press conference on the US participation at the 2019 Thessaloniki International Fair.
