Sorry to say bro but they did show the entire program and their coffins (if I remember correctly) and there was lot of crowd
So they gsvd the proof
Similarly u should give yours
That shows atleast 4 died, not that only 4 did.
It is not proven, by any means, especially since they initially aggressively hid casualties, that they didnt just put some troops in unmarked graves, or marked graves in civilian graveyards. It wouldnt be last time they hid and undercounted their dead, look at how Vietnam brutalised chinese when they tried invading veitnam and chinese still claimed they won.
