A/HRC/33/38 allegedly carried out by the United States Air Force in cooperation with the Government of Yemen as part of their campaign against suspected Al-Qaida affiliates. 41. Media reports indicated that on 22 March 2016, as many as 50 suspected Al-Qaida affiliates may have been killed by a drone strike in Al-Bayda Governorate. OHCHR was unable to verify those allegations or to understand whether civilians may have been killed or injured during the attack. It has been reported that on 27 March 2016, Ansar al-Sharia published a post on social media acknowledging the 22 March attack on its brigade. 14 B. Sieges and blockades 42. Since August 2015, residents in Taizz have witnessed a serious deterioration of the health situation and a near collapse of the health system as a result of the blockade imposed by the Popular Committees. In August 2015, the Taizz health office reported that, with the exception of the emergency unit and the kidney ward at the Thawra and Al-Jumhurri hospitals, all six public hospitals were no longer operational. Smaller private hospitals with limited capacity have been overwhelmed with the needs of those injured during the fighting. Furthermore, an outbreak of dengue fever exacerbated an already dire health situation for civilians stuck in Taizz; the Taizz health office reported 813 cases of dengue fever during August 2015. 43. OHCHR has observed a continuation of the naval blockade and restrictions on air and land travel imposed by the coalition forces throughout the period under consideration. According to humanitarian actors, the crisis has worsened as the harsh restrictions on imported vital goods have resulted in no fuel for water-pumping stations, hospitals and homes, and in a lack of medicine that has prevented the provision of adequate health care to persons with chronic ailments and those wounded by the violence. In areas under the control of the Houthi and/or Saleh-aligned forces, restrictions have included frequent denials of the movement-of-personnel requests made by humanitarian agencies and refusal to allow aid flows. C. Attacks on objects benefiting from special protection 44. Medical facilities, as well as educational facilities and religious and cultural sites, have repeatedly come under attack, despite the special protection afforded them. While the coalition forces have reportedly caused damage to protected objects mainly as a result of aerial attacks, the pro-Houthi and pro-Saleh forces have reportedly damaged protected sites through shelling and, at times, by allegedly positioning military objectives within the premises or surroundings of such sites. Al-Qaida and ISIL have carried out attacks on religious and cultural sites. Medical facilities and personnel15 1. 45. The following are three salient cases documented by OHCHR involving medical facilities and personnel.
