The 1961 Yassıada Trial after 1960 coup d'état accused Menderes and Foreign Minister Fatin Rüştü Zorlu of planning the riots. Though both of them rejected the claims, it is believed by scholars that Menderes assented to the organization of protests in İstanbul against the Greeks, but the extent of knowledge of Zorlu, who had been in London for the conference, is unclear. Interior Minister Namık Gedik was also accused of involvement, though he was not tried as he committed suicide before the trials started. According to Zorlu's lawyer at the Yassiada trial, a mob of 300,000 was marshaled in a radius of around the city for the attacks. The role of the National Security Service was not clarified at the trials, since the sole aim of the junta was to sentence the DP government.
