Rebel groups are reportedly continuing to recruit men and boys in camps in Chad that shelter 200,000 Sudanese who have fled the fighting in the Darfur region of their own country, and the Chadian Government must take all necessary steps to stop such activities, according to the United Nations refugee agency (UNHCR). "People who have fled the horrors of Darfur have already suffered enough," UNHCR spokesman told a news briefing in Geneva. "It is totally unacceptable that refugee camps become recruiting grounds and that children under the age of 18 are being victimized."
