Russian troops shelled the village of Shakhtarske in Ukraine's Donetsk Oblast on the morning of April 24, reported the regional prosecutor's office.
Two men aged 43 and 66 were killed in a house's yard, and their neighbor suffered shrapnel injuries, according to the prosecutors.
Shakhtarske is located in the Volnovakha district, about 75 kilometers from the Russian-occupied city of Donetsk.
Earlier the same day, Donetsk Oblast Governor Pavlo Kyrylenko said that Russian attacks had killed two civilians in the region and wounded two more over the previous 24 hours.
Ukraine's eastern Donetsk Oblast bordering Russia is the site of the war's fiercest fighting between Russian and Ukrainian forces as Moscow seeks to occupy the entire region.
