I can't speak specifically to that incident in that camp. What I can say is that in Jordan, the majority of refugees are actually not living in camps; they are living with host families.
Whether they are in camps or with host families, it creates added pressure on the limited resources already there. Most conflicts during these population movements usually arise from that increased pressure on the local resources. I can't speak specifically to that incident, but we have seen many indications of that, not only in Jordan, but also in Turkey and Iraq.
