It’s early yet, and some of this may be speculation — and I will make corrections below if I have got anything wrong here, but it appears that the guy who jumped into the octagon and attacked Conor McGregor, hitting him multiple times from behind is a friend (or even team mate) of Kabhib.
Meanwhile, while that was happening, Khabib jumped out of the octagon and started attacking Conor McGregors team mates. I will make further updates as information becomes available.
