GENEVA (Reuters) - Aid workers say fighting between rival military factions in Sudan is pushing poorly-funded humanitarian programmes in the region to a breaking point.

Even before the violence began on April 15, millions of people in Sudan and neighbouring countries were dependent on aid due to poverty and conflict. Since then, hundreds have been killed, including at least five humanitarians; food stocks have been looted; and many international aid workers have left.
