Ukraine LIVE: Putin Black Sea hell as just ‘8 troops, 2 ships’ left – naval boss ‘missing

Russia’s Donbas offensive is stalling, according to the UK’s Ministry of Defence.

British intelligence experts claim Russian forces have lost momentum and have fallen significantly behind schedule.

They also estimate that the Russians have lost around one third of the ground forces they committed at the beginning of the invasion in February.

The analysts wrote: “Russia’s Donbas offensive has lost momentum and fallen significantly behind schedule.

“Despite small-scale initial advances, Russia has failed to achieve substantial territorial gains over the past month whilst sustaining consistently high levels of attrition.

“Russia has now likely suffered losses of one third of the ground combat force it committed in February.”

They added: “Russian forces are increasingly constrained by degraded enabling capabilities, continued low morale and reduced combat effectiveness.

“Many of these capabilities cannot be quickly replaced or reconstituted, and are likely to continue to hinder Russian operations in Ukraine.”
