Hadji Mouhamadou Kandji, a military adviser at the U.N. Department of Peacekeeping Operations, said the tightening of an arms embargo had complicated the peacekeepers' task. "This calls for extra resources," he said in Dakar. A Security Council resolution this month authorised U.N. troops to enforce the arms ban by inspecting cargo shipments without notice at any port, airfield, military base or border. It also called on government and rebel forces to help the United Nations compile a list of all arms in the country, with an eye to eventual disarmament, and authorized the naming of a panel of experts to see if the embargo was being enforced. The 12-month mandate of the U.N. peacekeeping mission expires in April. Kandji said an evaluation would be carried out to see what was needed to improve resources.
