A/HRC/24/40 Government/AMISOM forces, was reported. While the number of fighters directly managed by the National Security Agency is unknown, reliable sources informally reported to the United Nations that approximately 2,000 fighters had been captured or had surrendered. After reception, AMISOM transfers such fighters to the National Security Agency for further proceedings. 62. In September 2012, over 280 ex-combatants were held in Masla, under National Security Agency/AMISOM custody. The legal status of such subjects was unclear, despite requests for clarification sent by UNPOS to AMISOM and to the Somali security forces. However, there are grounds to believe that this may amount to administrative detention. As all forms of detention, internment must be based on grounds established by the law and on procedures established by law; this does not currently seem to be the case. IV. Other developments during the reporting period A. Developments in the security and humanitarian sectors 63. The end of the Transitional Federal Government and its replacement in late 2012 by a Government that, although not chosen through a fully democratic process, is much more representative and popular than all previous governments; the establishment of a Parliament more representative and popular than before; the expansion of AMISOM/Somali security forces control over Mogadishu and most of the south-central region; and the dissolution of UNPOS and its replacement by the United Nations Assistance Mission in Somalia (UNSOM) under Security Council resolution 2012 (2013) of 2 May 2013 with a revamped protection mandate were among the most important developments during the reporting period. 64. On the military/security side, since the withdrawal of Al-Shabaab from Mogadishu in August 2011, the SNAF, with support of AMISOM and Kenyan and Ethiopian forces, has considerably changed the military context. The main cities in south-central Somalia, such as the strategic port city of Kismayo, Baidoa, Afgoye, Marka, Beledweyne, Jowhar and Hudur, among others, were recaptured. However, the recent Al-Shabaab takeover of Hudur and the devastating attacks against the regional court of Mogadishu, on 14 April, and on the United Nations common compound, on 19 June 2013, are reminders that the improvements will have to be consolidated and that insurgent groups are still capable of grave harm. 65. On 17 March, the AMISOM Force Commander confirmed the reoccupation of the key southern town of Hudur by Al-Shabaab fighters, following the announced withdrawal of the Ethiopian National Defence Force on 16 March. The sudden withdrawal of the Ethiopian National Defence Force from an area that it had been in control of since 2011 exposed the civilian population to Al-Shabaab. The latter’s recapture of Hudur led to the displacement of some 2,500 people, raising the overall level of those in urgent humanitarian need in that location to almost 6,000. 66. A more recent and critical development is the arrest and detention in Mogadishu of Sheikh Hassan Aweys, a prominent leader of Al-Shabaab, in early July 2013. It has the potential to influence other important developments in the political sphere. 67. In Kismayo, new clashes took place between two clans in June 2013. According to reports, the number of the victims of the fighting in Kismayo increased in early June to more than 70 dead and 200 wounded, with many victims among the civilian population. The controversy surrounding the role of AMISOM and the Kenya Defence Forces in the last round of fighting is ongoing. The deployment of African Union/United Nations 13
