It's on historical record that the first incident of violence against either community was instigated by the Turkish Cypriots and the TMT in 1958. They went on to murder innocent Greek Cypriots, women and children, as well as TCs who refused to go along with their separatist ideology:
On 12 June 1958 eight innocent and unarmed Greek Cypriot civilians from Kondemenos village were murdered by T.M.T. terrorists near the Turkish populated village of Geunyeli. That was the first incident involving human lives. According to the findings of the "Commission of Inquiry into the Incidents at Geunyeli" (appointed by the British colonial administration), which were also included in the official report of Sir Paget Bourke, Chief Justice of Cyprus, "for some days prior to 12 June, in fact from 7 June, inter-communal feeling was running very high in the island and there had been many instances of attacks by Turks, particularly in Nicosia, upon members of the Greek community and upon Greek property". There is no reference to attacks on Turkish Cypriots as there were no such attacks.
The T.M.T. terrorists attacked again in 1963. This is evidenced by the fact that they were found in possession of vast quantities of arms. Moreover, Turkish intentions were revealed in the "Deniz" incident when the Turkish ship full of arms was sent to Cyprus as early as 1959, after the conclusion of the Agreement on Cyprus.
And to quote "the New York Times" of 27.12.1963:
"Most of the fighting centered on a police station occupied by Turks in Nicosia, and on family apartments in the suburb of Omorphita. These were overrun and occupied by Turks who chased off Greek families. They were reported to have killed an unspecified number of women and children".
