Short story on monk fistfight lacks context

This CNN story details a fistfight between Christian monks of varying affiliation at the Church of the Holy Sepulcher in Jerusalem today.

The story reads like a crime story and, because of its length, I think, does not answer an important set of questions including what the historic tensions mentioned in the article are, where they came from, and how this fits into the overall realm of Christian experience in a religion that, at least theologically, isn't expected to put a lot of emphasis on locations.
