A/HRC/30/38 Paraguay 81. In relation to the general allegation of 7 October 2014 (see A/HRC/WGEID/104/1, paras. 97-107), while the Working Group appreciates the reply received on 7 January 2015 (see A/HRC/WGEID/105/1, paras. 111-115), it considers that more efforts should be made to establish the fate and whereabouts of the disappeared persons and to identify the bodies. Russian Federation 82. On 2 November 2006, the Working Group requested an invitation to undertake a visit to the country. No positive response has been received yet in spite of reminders sent. The Working Group hopes that a positive reply will be received soon. Rwanda 83. On 27 October 2014, the Working Group requested an invitation to undertake a visit to the country. The Working Group hopes that a positive reply will be received soon. Spain 84. The Working Group reminds the Government of its obligation to either investigate cases of enforced disappearances or, alternatively, cooperate with other countries who want to investigate and prosecute these cases, including by extraditing suspects present in its territory (see A/HRC/WGEID/106/1, para. 68). The Working Group emphasizes that, in accordance with article 17 of the Declaration, acts constituting enforced disappearance shall be considered a continuing offence as long as the perpetrators continue to conceal the fate and the whereabouts of persons who have disappeared and these facts remain unclarified. Sri Lanka 85. The Working Group appreciates the invitation received from the Government to visit Sri Lanka from 3 to 12 August 2015. It notes however that, on 17 July 2015, the Government has requested a postponement of the visit in the light of the proximity of the dates scheduled for the visit with the Parliamentary elections. The Working Group notes the commitment expressed by the Government to ensure that the visit can take place at a mutually agreed date before the end of 2015. Syrian Arab Republic 86. The Working Group continues to be gravely concerned about the situation in the Syrian Arab Republic, which may facilitate the occurrence of enforced disappearances. It reiterates article 7 of the Declaration, which provides that no circumstances whatsoever may be invoked to justify enforced disappearances. 87. On 19 September 2011, the Working Group requested an invitation to undertake a visit to the country. No response yet has been received from the Government in spite of reminders sent. The Working Group hopes that a positive reply will be received soon. 18
