That’s according to the Donetsk Regional Prosecutor’s Office, Ukrinform reports.

“On May 6, at around 14:20, the Russian invasion army launched an aerial bombardment on the town of Kostiantynivka, likely employing UMPB D-30 SM gliding munitions. The epicenter of the strike was in the densely populated area. As a result of the Russian attack on the front-line city, four civilians sustained bodily injuries of varying degrees of severity. Men aged 34 to 53 were taken to hospital with mine-explosive and shrapnel injuries injuries. Currently, they are being provided with qualified assistance, one of them being in grave condition,” the report says.

As a result of the explosion, three apartment buildings, a boiler room, and a car were damaged.

Under the procedural guidance of local prosecutors, a pre-trial inquiry was launched into the violation of the laws and customs of war.
