A/HRC/21/37 south of the country4 to target individuals described by Yemeni officials or international media as “militants”, “operatives” or “terrorists”. Repeat strikes, allegedly intended to kill persons who were trying to either rescue or bury victims, have also been reported. The delegation recalls the obligation of States under international law to conduct credible, prompt and effective investigations, and to ensure accountability in all such instances. D. Humanitarian situation 16. Despite some positive political developments, the humanitarian situation has worsened in Yemen over the past six months. Violence, insecurity and civil unrest have resulted in internal displacement and refugee and migrant inflows, economic decline and increased cost of living. Violence in Abyan and Shabwa has severely disrupted the delivery of basic social services, exacerbating widespread and chronic vulnerabilities.5 At the Friends of Yemen conference, held in Riyadh in May, donors pledged $4 billion in aid to help the Government of Yemen to strengthen its fight against Islamist militants and to develop its economy. 17. The World Food Programme (WFP), through a survey conducted during the reporting period, came to some alarming conclusions with regard to the rising levels of poverty, food insecurity and malnutrition. It found that half of the population in Yemen was malnourished and that prices of essential commodities had increased by 60 per cent since 2011. Furthermore, WFP and other aid agencies recently stated that 1 million children would become acutely malnourished during the coming months. The collapse of public services has left millions of people without access to health services, clean water and basic sanitation, which has resulted in increased incidents of communicable diseases. The Rural Water Sector Survey for 2012 showed that 30 per cent of water supply systems in Yemen were not functional. As a result, the entire country faces a water, sanitation and hygiene emergency. IV. Situation of human rights and implementation of recommendations A. Accountability and transitional justice 18. The events of 2011 brought the issue of accountability for past human rights violations to the forefront. Throughout the protests across Yemen, and the events that accompanied or were triggered by them, some 2,000 people are said to have been killed and approximately 22,000 injured across the country. 6 Various public facilities, as well as private and State buildings, were partially or completely damaged, mostly as a result of heavy shelling, crossfire or deliberate acts of vandalism. As such, there are persistent demands for accountability to bring perpetrators from all sides to justice and to provide redress for victims of these violations and their families. 4 5 6 See for example “Yemen: reported US covert action 2012”, The Bureau of Investigative Journalism, 8 May 2012.

These figures were released in 2011 by the Council of the Families of Martyrs of the Revolution, a non-governmental organization established after the events. They were repeated to the mission. The Government of Yemen has not published an official list of those killed or injured during the events. 7
