Ukrainian President Volodymyr Zelensky has accused Russian commanders of “craziness” in their efforts to capture the eastern town of Bakhmut.
The town – which sits in the Donetsk region and had a pre-war population of 70,000 – has been the centre of Russian attacks for months.
Despite a looming Ukrainian advance on the key city of Kherson, Mr Zelensky said the attacks continued in force.
Taking the town would be a symbolic victory for Russia.
“This is where the craziness of the Russian command is most evident,” Mr Zelensky said in his nightly address from Kyiv. “Day after day, for months, they are driving people to their deaths there, concentrating the highest level of artillery strikes.”
