The government army in the Democratic Republican of Congo has pushed rebel forces five km back in the vicinity of Goma. These rebels are north and west of Goma. Of particular importance is the effect on some sixty thousand refugees who camped out in the vicinity of Kibati, which is north of Goma and between the rebel forces and the army forces. At present, opposing troops are essentially staring at each other across often very short distances. UN forces are trying to separate the factions, but the best they are likely to do is to reinforce Goma so that rebels do not take over that city.
What are each side of the conflict fighting for? I don't understand... What problems could cause a war with so much death?
