Adam C. Bouloukos, director of the United Nations Relief and Works Agency (UNRWA) in the West Bank, has called for respect for international humanitarian law as civilians struggle in desperation amid the ongoing Israeli-Palestinian conflict. According to Bouloukos, some 670,000 displaced civilians are taking shelter at the UN's 149 campsites in Gaza, where Israeli air strikes have killed thousands. Apart from living under the shadow of violence, refugees are facing severe supply shortages, from water and nourishment to electricity that powers hospitals.
