British intelligence reveals why Russian troops leaving Kyiv

Some Russian units suffering heavy losses in Ukraine had been forced to return home and to neighboring Belarus, British military intelligence said, Report informs referring to Reuters.

Russian forces have halted the invasion on most fronts, and some analysts noted that Russia's promise to reduce fighting mostly covered areas where it has been losing ground, even as civilians remained trapped in besieged cities in the south and east.

Heavy losses and the withdrawal of some troops was impacting Russian operations, said Britain's defense ministry.

"Such activity is placing further pressure on Russia’s already strained logistics and demonstrates the difficulties Russia is having re-organizing its units in forward areas within Ukraine," it said in an assessment on March 30.

Russia is likely to continue to compensate for its reduced ground maneuver capability through mass artillery and missile strikes, the ministry added.

Russia has failed to capture any major city in its month-long invasion, while Ukrainian forces have made advances, recapturing territory from Russian troops on the outskirts of Kyiv, in the northeast and in the south.

“It is highly likely that Russia will seek to divert combat power from the north to their offensive in the Donetsk and Luhansk regions in the east,” Britain's Ministry of Defense earlier said.
