No man, they don't still have a presence, that's just something they've said to make it not look like a loss. For all intents and purposes Russia fully controls Bankhmut. I think people need to think critically about what they're actually posting here, you know both sides use propaganda, right?
I read Russia had 5x as many losses as Ukraine in Bakhmut, that would also seem wildly unrealistic. If they were to say they had 80% of the losses then I could believe that, but 20%? Maybe if it were Royal Marines fighting against the Russian regulars.
I'd also like to suggest it was strategically stupid to use so many Ukrainian resources fighting over Bakhmut that could have been better utilised. I'm sure that would've been against all the advice given.
