An intelligence update from the Department of defence of the UK comment regarding the Russian attack against Ukraine on 28 April. If this winter, the Russians have chosen Ukraine's energy infrastructure as their target, now they are hardly interested in it. There are also differences in the nature of long-range strikes.
"The wave involved fewer missiles that those over the winter and was unlikely to have been targeted Ukraine's energy infrastructure. There is a realistic possibility that Russia was attempting to insert Ukrainian reserve units and military supplies recently provided to Ukraine," the MoD.
Even if the Russians were aiming at the clusters of weapons, they still ended up in a residential building. 23 people died.
