Isn't it odd that so few Faunus got out of those Grimm-infested tunnels? At least some must have been killed by falling off a fast-moving train but the Paladins should have protected at least some and we know that aura makes Remnant life-forms incredibly tough and resistent to injury. So, what did kill the others? Answer: The Grimm.

Conclusion: Grimm target Faunus as much as humans. Well, they probably didn't make it out of the tunnel given that they would have had to walk all the way to an exit and proceed to some safe base. It is established that Grimm do attack other living things if they feel threatened or encroached upon. Given all the explosions and such, I imagine the Grimm would be in a mood to attack basically anything that wasn't Grimm.
