Current theory is that Russians told Ukrainian general staff that there was going to be a prisoner exchange that would be delivered by IL-76, but miscommunication led to nobody on the ground getting the news. I don’t believe Ukrainian AD was acting out of malice.
We know a prisoner exchange was supposed to happen at the border near Belgorod, we know IL-76s were used to transport POWs in the past, and we also know Ukraine shot down the IL-76. We also know Russia doesn’t usually operate IL-76 so close to the Ukrainian AD umbrella, so…
