Alright Sheb, time for me to come back from that "obvious propaganda"
First of all, I couldn't find any current or at least recent maps of the frontline on the Ukrainian side, so here's a Novorossiyan one:
So as we can see, assuming, of course, that the map is oriented top-north and left-west, is that the rebels' positions are generally to the east of the poor Volnovakha ("Волноваха," circled red by yours truly), and the AFU are generally to the everywhere else. And the fire was from the north-north-east.
If we assume that the "Grad" shells fired were of the most common M-21OF type, they couldn't have come from Donetsk, because the maximum range of these things is 20.4 km, so it was either the AFU that occupies the obtuse bulge to the south of Donetsk that fired these missiles (yes, that's a provocation theory, no, I'm not going to discard it on the basis of just that, although I am not going to think it's likely, either) or that the rebles in Еленовка or Докучаевск fired those shells at the AFU positions (blue dash-line represents AFU troop concentrations and the spiked line represents fortifications and entrenched forces, we can see that there are Ukrainian enthrenched forces to the north-north-east of Volnovakha) that were close to the Volnovakha and missed.
In any way, considering that the entire war has so far been an MRLS-fest of horrible proportions, and that those things are, by definition, inaccurate, I'd say it's most likely that nobody deliberately shot at Volnovakha, and that whoever did it simply missed. And all this noise around that one bus becomes rather questionalbe, if you ask me, considering that the AFU deliberately shells the rebels' civilians and infrastructure, but apparently that's how propaganda works.
Sheb: The Moscow Times is part of Sanoma group (which is Finnish) and is a lately force-registered "foreign agent" in Russia.
That said, Sanoma's magazines and newspapers are pretty leftist and tend to avoid saying anything bad about Russia and keep avoiding sensitive subjects in general (I suppose bashing right wing populist idiots is easier and safer).
Unfortunately, Russia has a problem with the lower echelons of our executive government powertripping and starting to, essentially, bully businesses and publicatons with moronic interpretations of laws, such as forcing everyone and their mother to register as a foreign agent if they recieve at least one cent of funding from abroad.
As for the films, nothing will happen. Our Cultiure Ministry funded anti-Russian чернуха such as "Burned by the Sun 2" in the past, it funds anti-Russian чернуха such as "Leviathan" in the present, and it will continue to fund anti-Russian чернуха in the future. What's going on is probably Putin saying to the Culture Ministry "Why the hell are you giving money to shoot films that pour mud on Russia? We are in the middle of a propaganda war, for Christ's sake!", and the Culture Ministry going entirely overboard in its response. But there will be no actual consequences of this, just as there are no actual consequences of that "No Gay Drivers law,"
which was widely misreported in the Western media, anyway.EDIT: fixed wrong wording.
