"The increased use of unguided munitions has led to the widespread destruction of built-up areas in the Donbas and has almost certainly caused substantial collateral damage and civilian casualties," the military intelligence tweeted on June 4.
Moscow has made seizing the whole eastern Donbas region a key objective of its unprovoked invasion after being pushed back from Kyiv.
