Consider whether this is your conflict. I have a rule in my family that I now apply in the workplace also: If the conflict is between other people and does not directly impact me, I inform each of the people in the conflict that I respect them both and trust them to resolve the dispute when they are ready. I ask them not to gossip to me about the others, and (to the best of my ability) I treat them as I would have before I became aware of the conflict.
