Sudan: In Sudan's refugee camps, tensions rise over water

Fighting has broken out over scarce water supplies in Kalma, the largest camp for internally displaced people in Darfur, western Sudan. Organizations working in the area say there are many fights in several camps, sparked by water shortages during one of Darfur's severest droughts in 50 years. Officials previously described the situation as an "emergency," although round-the-clock efforts have delivered some relief.
