UN Secretary General Koffi Annan is warning the humanitarian crisis in Darfur is worsening by the day. Half of Darfur’s civilians are completely cut off from humanitarian aid. Getting to the other half is fraught with risk. Villagers are fleeing in massive numbers reporting “indiscriminate killings, rape and abduction.” The situation has worsened since rebels reached a peace agreement with the Sudanese government in May. Fighting has increased between them while the Sudanese-backed militias have stepped up attacks on humanitarian workers and UN troops.
