 The United Nations Refugee Agency says thousands of villages in Burkina Faso urgently need water, sanitation, shelter and medical care, having fled their homes after Saturday's massacre by slummished militants. A UNHCR spokesman praised the generosity of people in other villages in welcoming and sharing what little they had with more than 3,300 who fled Sohan. The agency was working with the Burkina government to build shelters and help the displaced but more resources were needed. Up to 160 people were killed in the attack on Sohan. The UN says nearly 40 are seriously injured and in the hospital.
