ANKARA — The Turkish opposition website Nordic Monitor claimed that the Turkish military planned to invade Greece on June 13, 2014 using the code name Caka Bey, the name of an 11th Century warlord defeated in battle and killed by his son-in-law.

The site posted what it said was the tops-secret plan and indicated it's still on the table as an option as tensions are rising between the countries over constant Turkish provocations in the Aegean and East Mediterranean.

The classified documents related to the Turkish plan were inadvertently leaked during a prosecutorial investigation in the wake of the 2016 coup against the Erdogan government, the site said without explaining why they're being revealed only now.

The documents cited were part of a PowerPoint presentation that was supposedly planned by the Turkish general staff for internal planning review with the site suggesting it could still be used.

Also included in the same document were plans to invade Armenia, the operation in this case being titled TSK Altay Harekât Planlama Direktifi, which was dated August 15, 2000, The Jerusalem Post said.

The documents were exchanged by General Staff commanders via a secure internal email system, the site said, indicating military leaders panicked over the possible leaking of the classified documents and urged the court to allow the documents to be screened before being presented but that prosecutors didn't comply.

Chaka Bey is a much revered figure in Turkey, with the Turkish Naval Command listing him as the first Turkish admiral and founder of the first modern Turkish navy, and even has a statue of him in their museum in Istanbul, the site reported.
