A/HRC/21/18 Belarus 22. In November 2011, during its forty-seventh session, the Committee against Torture considered the fourth periodic report of Belarus (CAT/C/BLR/4). Andrei Bondarenko, Director of Platforma, an institution whose work is focused on the rights of persons in detention, was among the contributors to a joint NGO report submitted in connection with the Committee‟s consideration of the report of Belarus. Mr. Bondarenko also participated in a NGO briefing to the Committee and was present during the public consideration of the report by the Committee. 23. On 15 March 2012, Mr. Bondarenko reportedly learned that he was temporarily forbidden to leave Belarus when he was forced off a train between Minsk and Warsaw at the Brest-Centralnyj border control, on the first occasion he had attempted to leave Belarus since his visit to Geneva in November 2011. While the travel ban did not explicitly indicate that his advocacy work in Geneva was its direct cause, his work as a human rights defender, including his participation in the session of the Committee against Torture, was allegedly a decisive factor. Information received indicating that the case forms part of a pattern of travel bans issued in February 2012 against Belarusian human rights defenders is a matter of concern. China 24. In November 2011 and May 2012, the NGO Chinese Human Rights Defenders conducted training sessions on international human rights law and related mechanisms for human rights defenders from China in Geneva, as it had done annually for the past seven years, to coincide with the sessions of the Human Rights Council and relevant treaty bodies. Participants in earlier trainings had engaged with special procedures and the universal periodic review mechanism. Information received alleges that each year, Chinese officials had intimidated participants and prevented several from attending the training. Prior to the May 2012 training, four persons were reportedly prevented from attending: one person‟s family was threatened, another‟s supervisor blocked participation and two persons were stopped at different airports on departure on the grounds that their departure would entail “national security risks”. The passport of one was confiscated. Upon their return to China, various participants who attended the training sessions were questioned by security officers and the local bureau of justice. This practice is a matter of concern. Colombia 25. While undertaking his military service with the 14th Battalion of the 14th Brigade based in Puerto Berrio, Antioquia, between 2004 and 2006, John Fredy Ortiz Jiménez reportedly witnessed several extrajudicial executions of civilians presented by the army as “falsos positivos”. In 2008, Mr. Ortiz Jiménez publicly denounced the executions he had witnessed and the modus operandi of falsos positivos. Mr. Ortiz Jiménez met with the Special Rapporteur on extrajudicial, summary or arbitrary executions during his visit to Colombia in 2009. Mr. Ortiz Jiménez alleges that he has since been the victim of death threats, monitoring and two attempts of enforced disappearance, allegedly by members of the armed forces. 26. On 7 March 2012, it was reported that several persons beat Mr. Ortiz Jiménez and injured his arm, while trying to drag him into a vehicle in Barranquilla. On 10 May 2012, one day after he met with an OHCHR official, Mr. Ortiz Jiménez was threatened by two persons in a street in Baranquilla who demanded: “What were you doing with the UN woman yesterday?” 27. Reportedly, the protection programme of the Colombian Attorney General‟s Office provided some protection for Mr. Ortiz Jiménez. However, after the birth of his daughter, 7
