Russian forces killed 10 civilians in the Donetsk region, according to regional governor Pavlo Kirilenko in a Facebook post on Wednesday.
"Russia is killing civilians! On May 18, the Russians killed 10 civilians in the Donetsk region: seven in Lyman and three in Bakhmut. Two children were killed: one in Lyman and one in Bakhmut," said Kirilenko, who is head of the Donetsk region military administration.
Kirilenko said seven more civilians were injured on Wednesday.
"It is still impossible to determine the exact number of victims in Mariupol and Volnovakha. All Russians will be held accountable for these crimes!" he added.
Some context: Ukrainian officials in Donetsk said the whole front line is being "shelled day and night" by Russian forces. Kirilenko said that settlements — namely Bakhmut, Kostiantynivka and Soledar — more than 20 kilometers (about 12 miles) from the front line were also being attacked with airstrikes.
