A/HRC/33/51 IV. Observations 81. In addition to the observations formulated in its post-sessional documents (see para. 7 above), the Working Group makes the following country-specific observations based on the cooperation received and on significant developments regarding its mandate during the whole reporting period. Algeria 82. The Working Group reiterates its disappointment (see A/HRC/30/38, para. 58) that, in spite of an official communication received in February 2014 in which the Government invited the Working Group to visit Algeria during the second semester of 2014, it has not accepted the different dates offered by the Working Group. The Working Group continues to hope that it can soon be allowed to conduct a visit to the country. Bangladesh 83. The Working Group reiterates its regrets that no information has been received from the Government in connection with two general allegations transmitted on 4 May 2011, concerning the alleged frequent use of enforced disappearance as a tool by law enforcement agencies, paramilitary and armed forces to detain and even extrajudicially execute individuals (see A/HRC/22/45 and Corr.1, para. 33, and A/HRC/30/38, para. 61); and on 9 March 2016, concerning the reportedly alarming rise of the number of cases of enforced disappearances in the country (see A/HRC/WGEID/108/1, para. 6). 84. On 12 March 2013, 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. Burundi 85. The Working Group is concerned about the ongoing situation of violence and instability in Burundi, 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. 86. On 27 May 2009, the Working Group requested an invitation to undertake a visit to the country. Despite reminders sent, no response yet has been received from the Government. The Working Group hopes that a positive reply will be received soon. Congo 87. The follow-up report on the implementation of the recommendations made by the Working Group after its visit to the Congo in 2012 (A/HRC/19/58/Add.3) can be found in document A/HRC/33/51/Add.4. The Working Group regrets that the Government of the Congo did not cooperate with the Working Group in the process of producing the follow-up report. It hopes that the recommendations contained in the report will be duly and promptly implemented. 19
