[1] According to an Istanbul Police report, the plan was masterminded by İbrahim Şahin and was devised by Ergenekon, and has links with the Zirve Publishing House massacre.
[3][4] Yeni Şafak claimed in 2010 that according to documents retrieved by police, Şener Eruygur had attended Cage Plan meetings.
[5] The plan first came to light when prosecutors were told anonymously of the Rahmi M. Koç Museum finding explosives in the bottom of an exhibited submarine in December 2008.
[9][10][11] The plan allegedly calls for political terrorism and assassinations to be enacted against various groups of Eastern Orthodox, Armenians, Kurds, Jews and Alevis.
[13] It has been suggested that the plan had already begun to be put into effect when it was exposed: in mid-2009 colored stickers had appeared (and just as suddenly, disappeared) on the doors of hundreds of non-Muslim households in Kurtuluş, an incident that remains unexplained.
