The agency quoted representatives of the self-proclaimed Luhansk People’s Republic as saying that the accident occurred late Sunday evening.
Two days ago, the Joint Operations Force of the Ukrainian army said that two soldiers were killed and four others wounded, in shelling targeting them in the east of the country.
Russian media reported at the time that a shell hit a house in a Russian village near the Ukrainian border, causing damage to its roof, but no one was hurt.
Ukraine has strongly denied two previous reports that shells fell on Russian territory near the border, describing them as fake news.
