im not a conspiracy theorist at all, but I’m very surprised at the idea that Ukraine attacked Bolgorod. If im not mistaken, this is the region that came out in large numbers in support of the Wagner ‘uprising’ against Russian control, it has a large number of Ukrainians living there and public opinion is against Russian involvement in Ukraine.
It would be a very very odd target for them to choose.
Much better explanation is shot down missiles hitting civilian areas.. OR Russia up to their old tricks again.
