of the eastern regions. Of those killed, 59 were Ukrainian soldiers; the others were reported to be residents. 293 were wounded as a result of these security operations in the Donetsk and Luhansk Regions. This is a considerable increase since 14 May, when the Prosecutor General had announced 68 killed (servicemen and residents). 167. The HRMMU is trying to verify these allegations and to obtain disaggregated data on the victims and perpetrators. This is, however, difficult to obtain due to either a lack of, or contradictory, information. 168. On 13 May, a Ukrainian military unit was ambushed near Kramatorsk, killing seven Ukrainian soldiers. On 22 May, 17 Ukrainian servicemen were killed and 31 injured near Volnovakha (south of Donetsk); that same day another soldier was killed and two others injured in an attack by armed men on a convoy of military vehicles near Rubizhne in the Luhansk region. On 23 May, the territorial defence battalion “Donbas” was ambushed and attacked by an armed group, reportedly controlled by Igor Bezler, near the town of Horlivka close to Donetsk. Nine soldiers were wounded and detained by Bezler’s group; one was reportedly killed. On 29 May, a Ukrainian military helicopter was shot down near Slovyansk, which killed 12 service personnel who were on board, including a General. 169. On 26 May, fighting broke out for control of the Donetsk airport between the armed groups and the Ukrainian military. Ukrainian military planes and helicopters were used against the armed groups who eventually conceded control. The airport terminal and the runway were damaged as a result of aerial bombing. According to the Interior Minister, there were no losses within the Ukrainian military but according to various sources, the armed groups suffered over 50 casualties, of these at least 31 volunteers were reportedly from the Russian Federation, including from Chechnya and other republics in the Northern Caucasus. Out of these casualties, 30 bodies of those fighting with the armed groups have not been recovered. 170. During the fighting around Donetsk airport on 26 May, the Mayor called on the population not to leave their apartments unless absolutely necessary. Notwithstanding, residents did become victims. A woman was killed by a shell at a bus stop. A man was killed as a result of an incoming explosion near the Children's Hospital, with a further six people wounded, including a seven-year-old boy who was at home. A criminal case was opened under Article 258, Part 3 of the Criminal Code of Ukraine (“Terrorist act that led to the death of a person”). 171. On 2 June, an explosion of an unknown nature took place at the occupied building of Luhansk Regional State Administration. According to various accounts, it was either a failed attempt by the local armed groups to hit a Ukrainian fighter plane, or the bombardment of the occupied building by a Ukrainian plane. Seven people in, and around, the occupied building were reported killed as a result of the shelling, including the “minister of health” of the “Luhansk People’s Republic”, Nataliya Arkhipova. 172. The Ukrainian National Guard took control of the town of Krasnyi Liman (20 km North- West of Slovyansk) after fierce fighting on 3 June. The town hospital was badly damaged reportedly by shelling and most patients were evacuated to the basement of the hospital. 99 | P a g e
