36 CYPRUS v. TURKEY JUDGMENT accompanied by arrests and killings on a large scale. The Commission correctly described the situation as life-threatening. The above-mentioned broadcast statement of Mr Denktaş and the later report of Professor Küçük, if not conclusive of the respondent State's liability for the death of missing persons are, at the very least, clear indications of the climate of risk and fear obtaining at the material time and of the real dangers to which detainees were exposed. 134. That the missing persons disappeared against this background cannot be denied. The Court cannot but note that the authorities of the respondent State have never undertaken any investigation into the claims made by the relatives of the missing persons that the latter had disappeared after being detained in circumstances in which there was real cause to fear for their welfare. It must be noted in this connection that there was no official follow-up to Mr Denktaş's alarming statement. No attempt was made to identify the names of the persons who were reportedly released from Turkish custody into the hands of Turkish-Cypriot paramilitaries or to inquire into the whereabouts of the places where the bodies were disposed of. It does not appear either that any official inquiry was made into the claim that Greek-Cypriot prisoners were transferred to Turkey. 135. The Court agrees with the applicant Government that the respondent State's procedural obligation at issue cannot be discharged through its contribution to the investigatory work of the CMP.

Having regard to the above considerations, the Court concludes that there has been a continuing violation of Article 2 on account of the failure of the authorities of the respondent State to conduct an effective investigation aimed at clarifying the whereabouts and fate of Greek-Cypriot missing persons who disappeared in life-threatening circumstances. (b) Article 4 of the Convention 137. The applicant Government requested the Court to find and declare that the circumstances of the case also disclosed a breach of Article 4 of the Convention, which states as relevant: “1. No one shall be held in slavery or servitude. ...” 138. The applicant Government contended that, in the absence of any conclusive findings that the missing persons were now dead, it should be presumed that they were still being detained in conditions which, given the
