According to Ukrinform, the UK Ministry of Defense said this in its latest intelligence update published on Twitter.
"Russia has likely resorted to an increasing reliance on indiscriminate artillery bombardment due to a limited target acquisition capability, and an unwillingness to risk flying combat aircraft routinely beyond its own frontlines," the ministry said.
It added that in the coming weeks, Russia is likely to continue to rely heavily on massed artillery strikes as it attempts to regain momentum in its advance in the Donbas.
According to the update, in the Chernihiv region north of Kyiv, approximately 3,500 buildings are estimated to have been destroyed or damaged during Russia's abandoned advance towards the Ukrainian capital.
"80% of the damage has been caused to residential buildings," the ministry added.
