Two Russian commanders have admitted to killing hundreds of Ukrainian civilians, including 40 children, as well as "tossing grenades" at injured prisoners of war.
Commanders from the Russian paramilitary organisation known as the Wagner group have made the claims in video interviews posted by a Russian human rights organisation.
Alexey Savichev and Azamat Uldarov said they, along with other mercenaries, massacred between 300 and 400 people, including about 40 children who were taking refuge in the basement of a nine-floor block of flats in Bakhmut.
