I am not sure how much of this has been mentioned already as I am just dipping in and out and don't have time to read all the posts, but in relation to the Minsk agreement I found these two videos last night and they are quite horrifying to be honest, I didn't realise it was basically the Somme in eastern Ukraine and has been for years, starting in around 2014. The first video is by The Guardian and was made about 8 months ago and it of the Ukrainian side of the civil war (they call it a civil war) in the east of Ukraine, so it is all within Ukraine boders, the film takes you through the trenches and through the front line land - for people who don't like clicking on links it is called "on the Ukraine front line: 'only the dead aren't afraid' ". It won't show in youtube restricted mode.
And the second is even worse, it was filmed back in 2014 at the start of the civil war (they refer to it as the civil war). It is horrific. The man interviewed who says there were plants on the crowds to cause trouble to kick off is chilling, he says it while smiling! I am not familiar with the film maker, it is a group of films called Russian Roullette made around the same time. This unrest then turned into the civil war. There are quite desperate living situations on the Russian "side". For people who don't like clicking on links it is in youtube and called "Protest Turns Fatal: Russian Roulette in Ukraine" (2014)
There is another film which I can't find now which shows recent footage from the Russian "side", or the "separatists" side. Again, looked horrendous. From what I could gather they are very cut off, food problems and in places quite lawless, I think?
The recent films refer to the Minsk agreement but basically both sides "wait" for the other side to shoot before shooting to follow the rules from the peace agreement, but it means the fighting continues, no change
It looks like the Ukraine side got weapons from the West and the russian side from Russia. There has been a couple of meetings between Russia and Ukraine and between Russia and the US about this in the last couple of years but they were not fruitful
