The United Nations states that 35 civilians were killed and 143 were wounded in military conflict in Donbas in the period from March to May 14. This is said in a humanitarian bulletin of the United Nations Office for the Coordination of Humanitarian Affairs (UN OCHA), Ukrainian News Agency reports. According to the report, since the beginning of the conflict (from April 14, 2014 to May 14, 2017) over 2,000 of civilians have been killed and approximately 7,000 - 9,000 of civilians have received injuries. Most of the casualties were due to shelling, detonation of mines and unexploded ammunition. According to the data from the Office of the United Nations Human Rights High Commissioner, in March-April the number of casualties among civilians resulting from mines and explosives increased by 94% to 70 people (22 dead, 48 wounded) to compare with the same period in 2016. At the same time, 74.3% of the aforesaid casualties occurred in the not controlled territory to which humanitarian missions have limited access. In addition, considerable damages to houses and objects of vital infrastructure (electric energy and water supply facilities, hospitals and schools) amplify needs of people living in war-torn areas. For example, repair of residential houses damaged by shelling accounted for over 80% of housing interventions since the beginning of 2017. Since the beginning of the year, 32 educational facilities received damages resulting directly from the actions attributed to the conflict. Of the aforesaid facilities at least 18 suffered minor destructions and 14 had to shut down indefinitely interrupting educational process for thousands of children for several days or even weeks. As Ukrainian News Agency earlier reported, in March the UN Human Rights Monitoring Mission in Ukraine released data stating 9,940 people have been killed and 23,355 have been wounded during the entire period of ongoing conflict in Donbas.
