The Twitter account you used as source is a far-right, pro-Russian troll. Not very trustworthy.

Where can we get Mariupol footage of whats happening now?

Don’t think the Kiev Independent guys have access to Mariupol right now, I just copy-pasted from Twitter one of the first results of “Mariupol new apartments” search. You’re right, most probably those reporting from inside Russian-controlled Mariupol are pro-Russian.

Russia's goal with Mariupol seems to be razing the damaged parts of the city to cover up the destruction and their war crimes (see the mariupol theater), and rebuild new buildings on top, to proclaim that it's now a much better city under russian leadership.

Of course, ukraine would probably have razed or reconstructed these buildings, but the russian way seems to be explicitly done as a cover-up and propaganda operation.

I really doubt they can afford that level of public spending in other cities, and I wouldn't be surprised to learn that these construction projects only cover a small portion of the destroyed buildings. To say nothing about the quality of the hastily constructed flats.

I wonder if Russia is letting Russians taking up residence in the new houses and what the consequences would be later.

Depends what you mean by Russian? If you mean someone who's first language is Russian, then not much will change.

Finished but with a lot of problems
