49. Further, the CPT expresses its misgivings about the fact that all foreign nationals seeking international protection, including families with children and unaccompanied minors from 14 to 18 years of age, were compelled to stay in the transit zones at Röszke and Tompa while their asylum claims were being processed. The Committee recommends that the authorities fundamentally revise their policy regarding the holding of foreigners in transit zones. As a matter of priority, an end should be put to the accommodation of unaccompanied minors therein. On a positive note, the Committee finds that the Hungarian authorities made efforts to provide decent material conditions in the transit zones and to maintain the premises in a good state of repair and hygiene. That said, the overall design of the transit zones was far too carceral. 50. In their response, the Hungarian authorities deny the CPT’s findings. Further, the authorities underline that Hungarian police officers do not escort foreign nationals to Serbia but to the other side of the border fence, to an area which is still Hungarian territory and from where they may reach the transit zones. 51. The subsequent periodic visit carried out to Hungary in November 2018 provided an opportunity to discuss with the authorities the key issues raised in this report. In addition, the CPT delegation carried out a follow-up visit to Csongrád County Border Police Division (Szeged, Moscow street) in order to examine whether certain recommendations set out in the report on the CPT’s 2017 visit to Hungary had been implemented. Report and response published in September 2018 (CPT/Inf(2018)42 and CPT/Inf(2018)43) Report on the ad hoc visit to the Republic of Moldova in June 2018 (prison hierarchy and inter-prisoner violence; conditions of detention in prisons) 52. The purpose of the visit was to assess progress made in implementing the CPT’s previous recommendations concerning the situation in prisons, in particular as regards the phenomenon of an informal prison hierarchy and the related problem of inter-prisoner violence and intimidation, as well as the conditions of detention of adult male prisoners. During the visit, the authorities, at both central and local level, acknowledged that the system of informal prisoner hierarchies still existed. The delegation noted that attempts were made in the establishments visited, with varying degrees of success, to address this deep-rooted problem. At Goian Prison for Juveniles in particular, genuine efforts were being undertaken to develop positive relationships between staff and juveniles and to ensure that no prisoner was in a position to exercise power over other inmates. However, the visit brought to light that, at Chișinău and Soroca Prisons, the root causes of the problem were far from being addressed and that these establishments still largely failed to provide for the most basic requirement of prisoners: a safe environment.
